Where to Buy Cold Mirrors

Edmund Optics offers different kinds of cold mirrors, including versions with 0° and 45° angle of incidence and high performance versions with multi-layer dielectric coatings.

Shanghai Optics is a custom optics manufacturer with over 55 years of optics manufacturing experience. Our cold mirrors are perfect for applications that require high reflectance in the visible spectrum and excellent transmission in the infrared. These cold mirrors are manufactured using a special proprietary all dielectric coating technique that yields the most durable commercially available product. Our cold mirrors will pass Mil. C-675, snap tape tests and are capable of operation at temperatures as high as 600°C. They will also operate and survive in extreme humidity environments. Cold mirrors are available from stock in one inch and two inch diameter round or one inch, two inch and four inch square configurations. Larger sheets are also available and may be cut into custom sizes.

EMF, a Dynasil company, offers high transmission cold mirrors that are an excellent choice for preventing undesirable ultraviolet and visible light from damaging or altering the spectral characteristics. It offers two designs for use at either 0° or 45° angle of incidence. These mirrors are typically produced using borosilicate or float glass but are also offered on specialized substrate materials to withstand extremely high-temperature applications.

EMF has supplied 700,000 cold mirrors to a global automotive components manufacturer without a single reported field failure.

VisiMax offers various kinds of optical filters, including filters to be used as cold mirrors, which reflect only visible radiation and thus help to reduce the heat low in optical systems.
