Knight Optical’s KG1 Heat Glass Filters for Heat-Sensitive Systems

21 Feb 2020

Knight Optical’s KG1 Heat Glass Filters for Heat-Sensitive Systems

Commonly used in lighting devices – such as protective filters for projector optics – and systems featuring heat-sensitive components, KG1 Heat Glass Filters help alleviate overheating issues. Thermally toughened to eliminate cracking from excessive thermal energy, and high in quality, our KG1 Heat Glass Filters are regularly integrated into such devices that receive too much incident IR transmission. 

 The KG1 Heat Glass Filters themselves are designed to transmit visible wavelengths to absorb heat, causing infrared (IR) wavelengths; therefore, preventing it from reaching your system. Although this capability makes the KG1 Heat Glass Filter a sought-after component for engineers and R&D professionals working on heat-sensitive systems; it's worth noting, however, that care should be taken in the design of systems using KG1 as the material is an absorptive blocker and will heat up with use.

Available from stock or – as with all our components – as custom-made optics for seamless integration with your project, our KG1 Heat Glass Filters meet a diverse range of requirements sought by heat-sensitive systems. By opting for tailor-made optical components, you can specify the shape, size, substrate, optical coating and tolerances best suited to your project. 

 Typical specs:

Material: Schott KG1

Shape: Circular filter, square filter

Dimensional tolerances: +/- 0.1mm 

Parallelism: 

Surface accuracy: <5(2) @633nm

Surface quality: 

 Quality you can rely on
