Abstract:
An interference coating (22) for reflecting both visible light and a portion of the region of the infrared spectrum is disclosed. The coating includes a dichroic structure of a plurality of layers of a material having a low index of refraction and a plurality of layers of a material having a high index of refraction. The coating has an average spectral high reflectance of at least 80% for wavelengths in the visible light section of the electromagnetic spectrum and of at least 50% for wavelengths in a portion of the infrared section of the electromagnetic spectrum at least 150 nm wide.
