Knight Optical’s Hot Mirrors for use in Heat-Sensitive Systems

13 Oct 2022

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’ specifications. 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.

Furthermore, Hot Mirrors can be used in photography, where some sensors are sensitive to IR wavelengths and in newer incandescent bulbs, increasing efficiency by redirecting IR frequencies back to the filament.

Typical specs:

Material:                                             Borosilicate

Shape:                                                  Circular Mirror, Square Mirror

Dimensional Tolerances:              +/- 0.1mm

Parallelism:                                        < 5 arcminutes

Surface Accuracy:                            < 5(2) @ 633nm

Surface Quality:                               < 40-20 Scratch/Dig

All our hot mirrors are fully inspected on their quality in our ISO 9001-certified, state-of-the-art Metrology laboratory, using our Zygo Verifire Interferometer and our Cary 5000 spectrophotometer. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components.
