Cold Mirror Description
Optical Cold mirrors reflect visible light while allowing IR light pass through but not using it. It can be used in such a system which need to split the heat of spectrum and wave band. When using them, visible light is reflected, and the hot part is transmitted.
Optical Mirrors designed for laser applications are optimized for the given laser wavelength, while optical cold mirrors are ideal for illumination systems where high temperature lighting is desired. Metal substrate optical cold mirrors are ideal for applications requiring a constant coefficient of thermal expansion between the Optical Mirror and the mount.
Difference between hot-mirror and cold-mirror
Cold-mirrors reflect visible light while allowing IR light pass through but not using it, they are ideal for illumination systems where high temperature lighting is not desired. Hot mirrors reflect harmful IR waveband which can produce heat, while allowing visible waveband to pass through.

|Surface quality||S1:40-20,S2 fine grinding|
Specific specifications can be customized upon request.
- Do not use cold mirror with high power laser and high energy pulsed laser. We can provide dichroic filters suitable for use with pulse lasers
- The backside of the cold mirror is not coated with AR, please use the dielectric coating side for visible light incident. The backside may have 10% of loss of energy and the ghost image may occur.
- The visible light is reflected, the UV (heat) is transmitted, avoid blocking the transmitted light by a reflective element which may hold the heat.
- The reflecting light may be mixed with infrared if the incident angle is other than 45 degrees.
