All Interlock® lenses from ZEISS offer extraordinary image quality with high contrast for technical and industrial applications. They feature an improved fixture for focus and aperture as well as a full metal housing for robustness. The lenses impress with their high image quality and precise manual focus. They are available with standard F-Mount and standard M42x1 Mount (45,5 mm Flange Focal Distance) for even more stability.

In the F-Mount version the aperture can be adjusted continuously by taking advantage of the de-click function, allowing precise exposure setting. The Interlock® familiy cover linescan sensors up to 43 mm (4k to 8k) or full frame area sensor with 24 x 36 mm (up to 42 Mpixel).

The ZEISS Interlock family consits of eleven focal lengths range from 15 mm to 135 mm. With additional focal lengths and improved fixations they complete the lenses of the ZEISS Classic family.

Stress Test

ZEISS lenses need to operate perfectly in extreme conditions, withstanding everything from scorching heat and bitter cold to sandstorms and severe vibrations. The video shows how ZEISS researchers systematically submit lenses to extreme stresses in order to arrive at findings that can help in future lens design and development. The video explains how a lens with fixing screws was tested regarding following norms:

  • DIN ISO 9022
  • DIN EN 60068-1: 1988-06
  • DIN EN 60068-2 Part 64: 2009-04
  • MIL-Std 810G

High-quality metal housing

Noticeable quality and high value stability qualify ZEISS lenses for decades of intense use. The high-quality craftsmanship of the all-metal mount, the metal housing and the aperture ring as well as the robust front bayonet ensure reliable results.

Heavy-duty fixtures for focus and aperture

ZEISS Interlock lenses are equipped with special screws to fix focus and aperture to get stable and reliable measuring results even in rough industrial conditions. Both the locking screws and the stable design make the lens inured to vibrations, improve measuring repeatability and avoid machine downtime.

ZEISS T* anti-reflective coating

The optical elements of ZEISS lenses feature T* anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavourable lighting conditions. The first coating techniques were employed by ZEISS as long ago as in the 1930s.

High image quality

The excellent image performance of the ZEISS Interlock lenses is sharply focused on the requirements of current and future high-performance digital cameras. Thanks to the low level of stray light allowed by the lens design, high-contrast images are also possible with increasing high dynamic ranges of the sensors (HDR). The minimization of coma, astigmatism and spherical aberrations enables constantly high resolution over the entire image field. The optics are designed to ensure full utilization of the performance provided by high-resolution camera systems.
