Quality and durability

ZEISS and precision are two words with the same meaning. Quality is anchored in the DNA of ZEISS and all users benefit from the durability of ZEISS products. Star projectors from ZEISS work reliably for many decades. The service life of the digital systems also far exceeds the industry standard.

Live presentations with synchronous control

Intuitive operation of many functions

In one hundred years of planetarium development at ZEISS, the operating concepts have been repeatedly adapted to the technological possibilities of the time. The daily rotation in the first projector was still limited to fixed speeds. The first standard automatic control system was introduced in 1968. Today, software and hardware offer unparalleled flexibility.

The world's first planetarium projector: Zeiss Planetarium (Model I)

The Zeiss Planetarium - later referred to as Model I - was presented to the museum advisory board and the public for the first time from October to December 1923 in the Deutsches Museum in Munich, which was still under construction. It showed 4500 stars, the Milky Way, the names of important constellations as well as the sun, moon and the visible planets. The daily rotation was possible in three speed levels, as was the movement of the changing stars over the course of a year. The precession rotation was also already integrated.

The first planetarium model was limited to the local pole height of Munich.

From Germany to the world: The second version of Zeiss Planetarium (Model II)

The first devices of the second model series after the projectors for Munich and The Hague (Model I) stand on wheels that are guided in rails in the floor and rise up to 5 meters in height. The separation of the fixed star sphere into two for the northern and southern sky and the division of the projectors for the sun, moon and planets into two frames results in the "dumbbell" shape still used today. It is the constructive solution which, with the introduction of an additional axis of rotation to adjust the latitude, enables the starry sky to be displayed independently of the installation site. By rotating around the longitudinal axis, the "dumbbell" also allows the precession to be displayed. The device, designed for large domes, already displayed 8900 fixed stars, brighter star clusters and nebulae using two 1000 W incandescent lamps. Didactic displays were also available: Meridian, equator, ecliptic, nautical triangle, horizon circles and year counter.

Initially, numerous cities in Germany built planetariums. The city of Vienna in Austria was the first outside Germany to move into a Zeiss planetarium. In the period up to 1939, Zeiss planetariums were built in Europe, the USA and Japan.

Over the years, the second version of the projector was equipped with a series of additional devices that enabled supplementary displays. Among other things, they were used to project the heliocentric solar system, constellation figures and shooting stars.

New beginning with universal projection planetariums in Jena: Zeiss Universal Projection Planetarium UPP 23/1 to 23/3

After the almost complete dismantling of the Zeiss factories in Jena between 1946 and 1947 on the orders of the Soviet occupation troops, it was doubtful whether planetariums would ever be built in Jena again. Design drawings, patents and production samples were no longer available, as they were transported to West Germany together with 84 leading employees when the Americans withdrew from Jena in June 1945.

The decisive factor for the resumption of planetarium production in Jena was the order to supply a planetarium projector for Stalingrad, today's Volgograd - a "gift from the German working people".

The planetarium projector in the Jena Planetarium served as a model for the reconstruction. The first universal projection planetariums were still closely based on the pre-war model, but were equipped with a new control panel. The daily and annual movement could be shown continuously for the first time.

From Germany to the world: Zeiss Small Planetarium (ZKP 1)

Based on the first small planetariums for training in astronomical navigation, the largest series of planetarium projectors from ZEISS with more than 250 copies was created in Jena. They were relatively simply built. Customers could even assemble them themselves. The projector offers an excellent starry sky with around 5000 stars, which is still very popular in many places. The control panel is located directly on the projector, which means the contact between the projectionist and the visitors is particularly close. The series was delivered between 1952 and 1977.

First model from the production in Oberkochen Zeiss Planetarium Model III

After the Second World War and the separation of Germany, both ZEISS factories in Jena and Oberkochen produced planetarium projectors until the reunification of Germany. The large planetariums of a development series from Oberkochen were labelled with Roman model numbers.

The post-war model III from 1957 from Oberkochen, recognisable by its supports with the grid structure, was based on the model II with some technical innovations.

New construction of the large planetarium from Oberkochen models IV and V

The Zeiss Planetarium Model IV was a new construction in the mid-1950s. Modern supports replaced the typical ladder-like supporting structure of the first large planetariums. A total of 18 devices were installed, mostly in large cities, from 1957 onwards. Their service life of 30 to more than 50 years is remarkable. Some projectors from this model series are still in use today.

The Model V series includes modifications to improve the displays and significant extensions to the range of functions. These include extensions for displaying solar and lunar eclipses, a projector zoom for Saturn, extended horizon lights, a cloud projector and additional didactic displays.

The first mid-planetarium from ZEISS - ZEISS SPACEMASTER Space Flight Planetarium (RFP)

The SPACEMASTER space flight planetarium, first presented by ZEISS in Jena in 1967, was designed for medium dome sizes of 12.5 m to 17.5 m in diameter. The planetarium projectors of this series closed the gap between the Jena small and large planetariums. The space planetarium is a completely new design. The built-in fourth axis of movement (vertical axis) made it possible to simulate realistic space flight effects for the first time. It was the first planetarium projector in the world to introduce the option of automatic program control as standard. The sun, moon, planets, the world of fixed stars, comets, artificial satellites, shooting stars, numerous didactic projections, panoramas and motion sequences from extraterrestrial viewpoints followed the control commands of a perforated tape. Space flight planetariums were produced in series in the 1970s and 1980s. The projectors from the first series were installed in Brazilian planetariums and some of them are still in operation today.

Successful redesign: Models VI and VI A

The Model VI, first introduced in 1966, offered numerous additions and improvements. More powerful lenses and new types of lamps with 1200 watts served to increase the brightness of the stars. Daily rotation and annual movements could now be used continuously over a large speed range. The sun and moon projectors were equipped with eclipse devices that allowed different types of eclipses to be shown in correct positions. For improved usability, the Model VI also received a redesigned control panel. The Model VI is one of the most successful planetarium models from ZEISS.

From 1976, automatic control was also available for the Model VI (Model VI A).

Modernization of the large planetarium in Jena: ZEISS Universal Projection Planetarium UPP 23/6 to 23/8

In 1967, ZEISS presented its redesigned large planetarium in Jena. New 1500 watt light bulbs increased the brightness of the stars with reduced diameters. The moon also received more light. The introduction of azimuth rotation (4th axis) made it possible to simulate space flights. The small projector globes now showed the constellations from the device. The control panel was also modernized. The UPP 23/7 model was the first large planetarium with a completely blue color scheme.

Moscow received the last device in the UPP series. The special feature is the first automatic control for a large planetarium.

The second generation small planetarium: ZEISS SKYMASTER small planetarium ZKP 2

As the successor to the first small planetarium ZKP 1 from ZEISS, the SKYMASTER ZKP 2 model series was a completely new development for domes with a diameter of preferably 6 m and 8 m. Equipped with a card control, the device enabled automated shows in a small planetarium for the first time. With its dumbbell design, the projector was not only reminiscent of large planetariums, its presentation capabilities also reached those of a large planetarium. The sun, moon and planets were given motor drives for geocentric display for any location on Earth.

The instrument supported astronomical education and navigation training with a variety of auxiliary lines and markings, including the hour circle and vertical circle, both of which could be controlled in their positions. The nautical triangle could thus be displayed for each star. The optical starry sky was optimized for small domes with approx. 6000 stars up to the 6th magnitude class. SKYMASTER ZKP 2 were delivered and installed between 1977 and 1992. The projectors from the last series (ZKP 2P) at the beginning of the 1990s already had computer control.

Space flight planetariums with direct programming: ZEISS SPACEMASTER RFP-DP, RFP-DP2 and RFP-DP3

The general development of control technology had a rapid impact on the SPACEMASTER model series. While the mechanical design remained largely untouched, several generations of automatic controls for the central planetarium from Jena followed. The original perforated tape was replaced by audio tape in the RFP-DP model in 1978. It made it possible to record control data and thus program commands directly with the operator. The first fully electronic control system based on microcomputers (RFP-DP2) followed in 1983. The projector received its third and final control update in 1988 (RFP-DP3), which also introduced a new ergonomic operating principle.

The 1980s outstanding projector for large planetariums: ZEISS COSMORAMA ZGP

In the 1980s, COSMORAMA was the most outstanding planetarium projector for domes with a diameter of 23 meters. ZEISS in Jena developed it according to the specifications of the original customer. It had a microprocessor control for all planetarium functions, which made it possible to switch between manual operation, direct programming and automatic playback. The device was equipped with every planetarium function imaginable at the time. In addition to the planetarium-specific control, parallel computer communication was possible for additional functions such as special effect projectors.

A total of four projectors were delivered. COSMORAMA was replaced at the end of the 1980s by the new UNIVERSARIUM model series, which was also suitable for inclined domes.

Medium planetarium from the Oberkochen planetarium workshop: Model 1015

The planetarium projector for domes with a diameter of 8 m to 15 m, known as System 1015, was characterized by its compactness. In terms of performance, it hardly differed from its big brothers. With around 5,000 stars, it is adapted to the optimal impression of the starry sky in the smaller domes. The electronic control was available with or without an automatic component. Thanks to its modular design, customers were able to adapt the functional equipment to their needs and budget.

Projector for inclined domes: Model VI TD from Oberkochen

The VI TD model is specifically designed for installation in large diameter inclined domes. It consists of the fixed star projector, which can be controlled in three axes, for displaying around 8,900 stars and the projectors for the sun, moon and planets with separate installation. The technological basis for the projector came from the Model VI. The new projectors for the sun, moon and planets had two axes of movement and an image rotation function. The joint astronomical positioning and movement was computer-controlled in real time. A classic control panel was used for manual operation. A programming option also allowed the automatic playback of functions.

Projector for inclined domes: STELLARIUM from Jena

In 1989, the Verne Theater in the Heureka Science Centre in Vantaa, Finland, opened with a new type of planetarium projector. It is the first Starball from the Jena Zeiss factory. It is also the first with fiber optics to illuminate the star masks. The Starball, together with the two separate projectors for the sun and moon, is the forerunner for the subsequent series of large planetariums of the UNIVERSARIUM Model VIII and Model IX series. The fiber optic technology makes it possible to multiply the brightness of the stars while significantly reducing the lamp power. The technology is currently used in all ZEISS planetarium projectors.

ZEISS East and West unites Model VII for the Forum of Technology

The former "Forum of Technology" at the Deutsches Museum in Munich included conference rooms, art house cinemas, a café, an IMAX cinema and one of the largest planetariums in the country. Inaugurated in 1993, it was undoubtedly one of the most modern planetariums in the world. The 20-metre dome housed a computer-controlled 3D laser system, numerous slide, effect and video projectors and offered 12,000 watts of sound. The centerpiece, however, was the star projector, the only planetarium projector that was developed by ZEISS in Oberkochen, but also contained components from ZEISS in Jena. Jena contributed with the fiber optics for the star projection. A unique projector that worked tirelessly until the closure of the Forum der Technik in 2005.

A new small planetarium with computer control

The small planetarium of the third SKYMASTER ZKP 3 series was based on the basic structure of the extremely successful ZKP 2. The increase in light output expanded the diameter range for the ZEISS small planetarium to 11 m in diameter. The projector had a modular design and the customer could decide for themselves on the scope of equipment. The projector brought a variety of improved mechanical properties and offered new projections: separately displayable constellation figures of the northern and southern sky and the zodiac, line projectors with optical imaging, a compass rose and a rotating map. PC-supported, the projector allowed all operating modes from live to fully automatic.

SKYMASTER ZKP 3 received several control upgrades, the ZKP 3/B version in 2004 and the ZKP 3/C version in 2012. The upgrades always included the latest hardware and software for control and operation.

UNIVERSARIUM Model VIII – Top class projector

UNIVERSARIUM is still the most powerful planetarium system from ZEISS. It is designed for large domes up to 50 m in diameter. The projector reflects the celestial phenomena realistically and precisely. The starry sky with 9,100 stars is shown using fiber optic projection systems. They ensure the brilliance of the stars: high brightness coupled with small diameters. Two special projectors show the brightest stars Sirius and Canopus. Variable stars are present with their main representatives Delta Cephei, Algol and Mira.

The projectors for the solar system bodies are separate from the star ball.

The astronomical movements are coordinated by software.

Two axes are used for spatial orientation, while the third axis takes image rotation into account. Zoom lenses allow the displayed objects to be enlarged while maintaining the same brightness.

The control is based on several microcomputers. All functions can be controlled interactively. Operation remains simple. All operating modes and functions are available with simple mouse clicks.

Newly designed STARMASTER central planetarium

STARMASTER is based on a completely new development. The astronomical projection system for medium dome sizes combines the advantages of the classic dumbbell design with those of the starball design for the first time. A compact sphere contains all projectors except those for the planets. The planetary projectors are separate and can be controlled independently of each other, while the projectors for the sun and moon are located directly on the central starball. Thanks to motorized shutter control, installation in inclined domes is possible.

The control system is based on that of its big brother, the ZEISS UNIVERSARIUM. This means that the overall ease of use, the integration into a complex ensemble of audiovisual, multimedia technology and the synchronization and communication with other planetarium systems are at the same top level as for large planetariums.

UNIVERSARIUM Modell IX – The most modern large-scale planetarium

The UNIVERSARIUM Model IX projection system for domes from 18 m to 50 m in diameter is based on the Model VIII concept and offers additional features and functions. The Milky Way has been refined. A new technology for the display of gas nebulae, galaxies and star clusters perfects the simulation of the night sky. A new projector, rotatably mounted on the Starball, projects the celestial equator and ecliptic to show the precessional rotation of the Earth. Projectors have also been added to illustrate galactic coordinates, the nautical triangle, twilight and to simulate moonlight. The display of the planets and planetary moons is variable.

The conversion of the operating software to a workstation basis gives the Model IX a high level of reliability and enables remote diagnostics and program exchange via the Internet. ZEISS offers hardware and software updates for older devices, which ensures further operational security.

Since 2015, the metal halide lamps for the fixed star and planetary projections can be replaced with modern, efficient LED light sources. This further improves the luminosity of the starry sky and saves energy.

ZULIP was a laser video projector that could be rotated on two axes and equipped with a zoom lens. The basis was laser display technology, with which a scanned laser beam draws a complete image. ZULIP produced a sharp image at any distance. The image quality came from the enormous contrast and the very high color saturation of the laser light. 

As the laser display technology caused relatively high service costs, this technology was not developed further.

SKYMASTER ZKP 4 is designed for domes with a flat horizon in the range of 6 m and 15 m in diameter and combines the most advanced technologies for brilliant projections with the most modern digital solutions. There are no longer any gears for controlling the movement of the sun, moon and planets. This is done with digitally driven axes and software control.

The planetarium projector, first installed in 2005, has excellent mechanical and optical precision. Highly developed projection systems with fiber optics form the basis for the best starry sky projection ever seen in the small planetarium.

With the use of power LEDs as a light source, the starry sky has been even more brilliant than ever since 2011. Older projectors can be brought up to date with an LED upgrade.

ZEISS SPACEGATE Fulldome Systems for small domes

SPACEGATE was a multi-channel, digital projection system for domes from 6 m to 15 m in diameter, first introduced in 2005. The projection was from the center of the dome. SPACEGATE was available in two versions: DUO – the two-channel projection for small domes and QUINTO – five channels for larger or more demanding installations.

ZEISS has been building core components for digital projectors since 1997. These were used in the SPACEGATE in-house development. DIGIGON lenses specially developed by ZEISS ensured exceptionally high image sharpness and uniform illumination.

Of course, the user benefits from being able to contact the projector manufacturer directly for maintenance instead of having to rely on an intermediary.

Since 2007, ZEISS has also been configuring and supplying fulldome systems with standard digital projectors from several suppliers. ZEISS sometimes integrates its own lenses and always uses its own lens solutions to optimize projection quality. The selection of projectors and the configuration of the respective system is always based on customer-specific requirements. The spectrum of projection solutions ranges from single-lens systems (fisheye projection) to 8k+ stereo projection. The projector selection and configuration takes into account contrast and brightness requirements, serviceability and is based on the customer's available budget.

In addition to projectors and lenses, the hardware and software used also influence the quality of the fulldome system. Here too, ZEISS relies on professional suppliers and its own solutions.

ZEISS VELVET digital projector: the first projector with absolute black in the images

The presentation of the VELVET projector at the IPS Conference 2008 in Chicago was a small sensation. With VELVET, ZEISS offers the world's first video projection with an absolutely black background. VELVET is an in-house development by ZEISS and impresses not only with its enormous contrast ratio of 2,500,000: 1, but also with its outstanding image quality thanks to the ZEISS DIGIGON lenses specially designed for dome projection.

ZEISS developed the VELVET projector primarily for fulldome projection in planetariums. The video projection can overlay the optical starry sky without destroying its brilliance.

The legendary projector was significantly improved in 2015 by replacing the halogen lamps with LED light sources. In the LED version it offers even more colors, higher sharpness and more details in the image. It also saves service time and minimizes operating costs.
