Knight Optical can offer Hot Mirrors for use in Heat-Sensitive Systems. We supply a range of hot mirrors for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specs. What’s more, our Hot Mirrors are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers working with Heat-Sensitive Systems. Hot Mirrors are designed to transmit visible wavelengths and to reflect heat, causing infrared wavelengths. Hot mirrors have a sharp cut-off between Infrared (IR) and visible because they have a dielectric coating that can be controlled for different AOIs (most commonly 0°). For systems that require heat shielding while still needing visibility, hot mirrors can be used. These can attenuate IR radiation and allow visible light, which permits your temperature-sensitive equipment to be visible.
