If you want to measure temperatures in a very wide range with an infrared camera, you normally do this in stages. The neutral density filters are changed gradually from time to time. Adjusted to a specific temperature range, they prevent high-intensity infrared radiation from striking the camera detector and falsifying the measurement result by depolarising the detector pixels.

Measurement and testing tasks that use infrared cameras often differ enormously. So what could be better than being able to use a camera that is exactly tailored to the specific application? Quite clearly, a camera that can solve very different tasks at the highest possible level.

New materials with precisely controlled optical and thermal transport characteristics can make a large contribution to resource-saving thermal management. Scientists of the University of Bayreuth are pursuing this vision.
