Knight Optical’s Custom Hot Mirrors for Heat-Sensitive Systems

18 Nov 2021

Knight Optical offers a wide range of Hot Mirrors for a variety of heat-sensitive systems. Due to their ability to transmit visible wavelengths and reflect heat, generating infrared wavelengths, Hot Mirrors are commonly specified for systems that require heat shielding while still requiring visibility. Thanks to their dielectric coating – which can be controlled for different AOIs (most commonly 0°) – our Hot Mirrors have a sharp cut-off between Infrared (IR) and visible wavelengths. 

Alongside an extensive stock range, we also offer a variety of custom-made Hot Mirrors to meet the specific requirements sought by your heat-sensitive application. This customised service allows you to specify the shape, size, tolerance and thickness of your component for seamless integration with your device. What's more, we also offer a range of optical coatings to enhance the operability of your application and protect those operating in harsh environments.
