Cold Mirrors reflect visible wavelength and Transmits IR hence it can be used to build projection systems without worrying about heat build-up with our 0° angle of incidence cold mirrors. The multi-layer dielectric coating on these glass mirrors reflects 90% of visible light while allowing better than 80% transmission of IR waves. Cold mirrors are ideal for illumination systems where high temperature lighting is not desired. Mirror will function satisfactorily and will not be damaged by exposure to an ambient temperature of -50°F to +450°F.
- Reflect IR
- Transmit Visible wavelength
Available for an angle of incidence of 0°, these heat reflecting mirrors can be used in a variety of optical systems where heat build-up is a concern. Applied mainly in projection and illumination systems, the multi-layer dielectric coating on the mirrors reflects harmful infrared radiation (heat), while allowing visible light to pass through. Hot mirrors make an intelligent addition to optical systems that could otherwise be damaged by excessive heat.
Note: Whenever using high power illumination, forced air cooling is recommended.
