Dichroitic reflectors

Dichroitic reflectors are special optical filters that consist of several layers of materials.
Certain wavelength ranges are reflected and let through.
They are often used in lighting applications to filter the light of incandescent lamps or halogen lamps and create a certain light color.
Through the targeted blocking of certain wavelengths of light, such as infrared radiation, dichroitic reflectors can also help to reduce the heat output and to extend the lifestyle of the lamps.
