In earth observation, for example, high-quality camera systems are used. They have a very high resolution to capture the events on earth in detail. However, disturbances during recording, such as movements of the atmosphere, can cause blurred images. The camera systems are therefore additionally equipped with stabilization elements, such as gyroscopes. In order to enable the high resolutions of such precision cameras, powerful and precise optics are required. Camera systems in satellites can also be modified for different spectral ranges, from ultraviolet to infrared beams. The optical coatings specifically separate parts of the received light signals. Adherence to the required quality and the special location require high performance, durability and particularly strong resistance of the optics to external influences.
