You will be amazed how easy imaging becomes when the AI Sample Finder automatically detects the sample carrier, adjusts the focus, and finds your sample region. Even with low-contrast samples, you will quickly obtain an overview image to access relevant regions with just a click. Reduce the time to image from minutes to just seconds and start your experiment right away. Let Smart Setup and the Focus Strategy Wizard guide you through the experimental setup for easy and intuitive selection of the imaging modalities for your applications. Using ZEN Connect, acquired images can be easily combined with electron microscopy data and other modalities.

ZEISS Axio Observer - Efficiency

Efficiency for Your Experiments

ZEISS Axio Observer - Efficiency

Expect a remarkable increase in efficiency with the automation functions of Axio Observer. Use fast switchable LEDs or go for powerful and economic white-light sources in combination with the fast filter wheel for highest spectral flexibility and speed. Select the ideal camera from the dedicated ZEISS Axiocam portfolio or from third-party suppliers: You will always get the image quality and speed your applications require. With Definite Focus 3, focus drift during complicated experiments is a thing of the past. Whether keeping your sample in focus for long-term imaging or adapting your objective to your sample, it's all automatic with this highly organized system.

AI Sample Finder

Automated sample identification for efficient imaging

ZEISS Axio Observer - AI Sample Finder

Microscopes are becoming increasingly automated. For sample placement, however, microscope parts such as the condenser arm often have to be moved manually. Focus adjustment and identification of the relevant areas on the sample carrier require additional manual steps. The AI Sample Finder automates this sequence, eliminating time-consuming manual adjustments and reducing the time to image from minutes to just seconds.

You can access all sample areas directly which allows you starting your experiment faster than ever. The AI Sample Finder greatly improves productivity as you can easily image only those regions containing sample not overlooking potentially important areas.

ZEISS Axio Observer - Apotome 3

Apotome 3

Optical sectioning using structured illumination

ZEISS Axio Observer - Apotome 3

Create optical sections of your fluorescent samples – free of scattered light. With structured Illumination, removal of out-of-focus light becomes simple and efficient, allowing you to fully focus on your research. Apotome 3 recognizes the magnification and moves the appropriate grid into the beampath. The system then calculates your optical section from a number of images with different grid positions. It’s a totally reliable way to remove scattered out-of-focus light, even in thicker specimens. Yet your system remains just as easy to operate as always. You get images with high contrast in the best possible resolution – simply brilliant optical sections.

ZEISS Axio Observer - Definite Focus 3

Definite Focus 3

Keep a sharp eye on your goals

ZEISS Axio Observer - Definite Focus 3

Acquiring time-lapse data from living samples can be tricky. Changing conditions such as room temperature influence the microscope as well as the sample carrier and can cause focus drift. Definite Focus 3 compensates for this drift and keeps your samples in focus. With higher accuracy and precision even your most challenging multi-day, multi-position time-lapse experiments will yield sharp and high contrast images.

Here’s how it works: an infrared LED is projected through a grid onto the bottom of the sample carrier. Any change in the focal position of the sample will be indicated by a change of the grid image on the carrier bottom. An integrated camera monitors the shift while the focus drive of the stand moves to compensate for the drift in real-time. Using ZEN imaging software, simply choose a focus strategy and set up your experiment: all compensation happens automatically in the background, without interfering with your acquisition.
