Switchable infrared filter for e.g. protecting infrared detectors, has carrier material with diamond foil having thickness of about ten to forty micrometers and very small thermal capacity, where foil is coated with dielectric layer
The filter has carrier material, and a filter layer that is made up of thermochrome material e.g. Vanadium oxide, arranged on the carrier material. A heating device is connected with the carrier material. The carrier material has a diamond foil with a thickness of about 10 to 40 micrometers and a very small thermal capacity. The foil is coated with a dielectric layer. The carrier material is also connected with a heat sink (4).
