04 Apr 2023 Hot mirrors are heat-reflecting mirrors that are designed to work as a shortpass edge filter by transmitting visible wavelengths @AOI 0°, while reflecting NIR, heat-generating wavelengths.(Reflect NIR heat & transmit VIS light @ 0°. Remove unwanted heat from an optical system.) Cold mirrors are heat-transmitting mirrors that are designed to work as longpass filters by reflecting visible wavelengths @AOI 45°, while transmitting NIR wavelengths.(Reflect VIS light and transmit NIR heat @45°.Remove unwanted heat from an optical system.)
