Where to Buy Hot Mirrors

Hot and cold mirrors are both specialized dielectric mirrors which are used for heat control; to filter unwanted energy from a light source. A cold mirror will reflect 90% of the visible light spectrum while efficiently transmitting (and thus removing from the site of interest) infrared wavelengths. A hot mirror will reflect 90% of infrared and near infrared light, and transmit a large portion of visible light (up to 80%). Shanghai Optics can manufacture custom hot and cold mirrors mirrors for any angle of incidence desired, from 0 to 45°.

Edmund Optics offers various speciality mirrors, including hot mirrors which reflect 90% of NIR and IR light. We also have extended hot mirrors with improved NIR reflectance and high performance versions with an optimized multi-layer dielectric coating.

VisiMax offers various kinds of optical filters, including filters to be used as hot mirrors, which reflect infrared radiation in order to reduce the heat low in optical systems.

Artifex Engineering offers custom hot mirrors tailored to your requirements for shape, coating and other specifications. Visit our product page for more information. We look forward to your inquiry.

EMF, a Dynasil company, has a large inventory of high transmission hot mirrors that are an excellent choice for preventing undesirable heat from damaging thermally unstable materials or altering the spectral characteristics beyond that position in a light path by reflecting infrared light while allowing visible light to transmit. EMF offers two designs for use at either 0° or 45° angle of incidence.
