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 for any angle of incidence desired, from 0 to 45°.

Dielectric mirrors, such as hot and cold mirrors, are specifically designed to regulate heat by filtering out undesired energy from a light source. Cold mirrors are capable of reflecting 90% of visible light spectrum and effectively transmitting infrared wavelengths, thereby removing them from the area of interest. On the other hand, hot mirrors can reflect 90% of infrared and near-infrared light while transmitting a significant portion of visible light (up to 80%). Avantier has the capability to produce tailor-made hot and cold mirrors for any angle of incidence, ranging from 0 to 45°.

Edmund Optics offers various specialty 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.

See us at SPIE Photonex UK 2024 in Manchester, UK, Oct. 30–31 (booth 208), Optics & Photonics Sweden 2024 in Gothenburg, Nov. 5–8 (booth LE 21), Compamed Düsseldorf in Düsseldorf, Germany, Nov. 11–14 (booth A8C11) and Advanced Solid State Lasers Conference in Osaka, Japan, Oct. 20–24 (booth 120)!

Knight Optical can provide hot mirrors from stock in 25 mm to 50 mm diameters or 25 mm × 25 mm to 100 mm × 100 mm squares, however these can be cut to custom dimensions with a quick turnaround. Hot mirrors reflect IR whilst transmitting visible light. These mirrors are an alternative to our KG1 heat filters which absorbs the infrared light rather than reflecting it.

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.
