Also known as: Heat Mirror, Hot Mirrors, DN Filters, Day and Night Filters
Functions: Heat reflection filters can reflect the ultraviolet and infrared rays of the light source while the visible light is high, and can reduce the temperature in the light source. Widely used in stage effects, building flooding, commercial space lighting, floodlights, moving lights, scanning lights, effect lights, wall washers, fiber optic lights or optical medical instruments, long-term use, high temperature resistance No release film.
Applications: Lighting, Stage Lights, Fiber Optic Lights, Optical Instruments.

1. Heat reflection filters are vacuum vapor-deposited with a multilayer dielectric film. The number of coating layers is about 36~48 layers, which can be changed according to customer needs.
2. Coating by PVD-EBGE (Physical Vapor Deposition-Electron Beam Gun Evaporation) .
3. The transmittance curves are measurements at 0°of incidence angle. No penetration by coating reflection.
4. The spectral curve is the measured value of the sample and may vary slightly depending on the manufacturing lot, but conforms to the spectral definition.
5. Round size "Dia" is an abbreviation for diameter, which represents the diameter of a circle.
6. The website specifications are for reference only, and shipments are subjected to the specifications confirmed by both parties.
7. The highest safe temperature refers to the temperature that the substrate can withstand under conditions of non-uniform heating or rapid temperature difference.
