Where do I find CAD models or technical drawings of my Xenics camera?

Our technical resources are located on the product page for the respective cameras. From our product catalog, look for the series your Xenics camera falls under.

Then, on the “Technical Resources” tab, you will find all the documents available for that product/camera.

If you do not find what you are looking for, no problem! Reach out to us and we will provide the specific documents or files you need.

What is a (mechanical) shutter and why does the camera needs this?

The mechanical shutter is an internal reference which the microbolometer requires to compensate on e.g. pixel drifts. Basically it is a black reference which is put in front of the detector, which takes reference images and corrects the pixel drift.

How can a user control the mechanical shutter to assure his image?

By factory default the shutter is initialized when the temperature at the detector changes by 0,5°C. An additional timing elapse function is also implemented and can also be activated. When a camera has just been started it will get to his working temperature. During this time the detector will warm-up and will be shuttered several times to assure the quality of the image.

On which cameras do you have a microbolometer with mechanical shutter?

Today our XTM cores and Gobi cameras have microbolometer detectors on board which utilize a mechanical shutter.

How is NETD measured?

NETD is one of the most important performance parameters for infrared imaging systems. It is a signal-to-noise figure which represents the temperature difference which would produce a signal equal to the camera’s temporal noise. In human language: NETD expresses the minimal resolvable temperature difference when the camera is used for relative imaging applications.

What is the thermal time constant?

The thermal time constant τth of a bolometer is determined by the thermal mass C and by the thermal conductance G between the pixel and its environment. It expresses the physical time a bolometer needs to heat up and give an electrical output that equals or represents the input. Typical values for A-Si are between 7 and 10ms.

How do Researchers Plan to Overcome these Technical Challenges?

Researchers are exploring novel materials, device architectures, and fabrication techniques to address the technical challenges in single photon detection.
