Knight Optical’s Wafers for substrates for IR Cut Off Filters

10 Apr 2018

When it comes to a high quality IR Cut filter, it is the substrate with the coating applied that affects the performance. Knight Optical provide high quality wafers for precisely this, and the surface quality of our substrates eliminates blotching at the sensor which occurs on lower quality substrates especially where IR Cut filters are concerned.

Our stock wafers are produced as thin as 500μm and provide exceptional surface quality. However, we can manufacture to a fully customised specification with a wafer thickness as little as 10 μm. Our substrates for stock or custom can be manufactured from a great deal of materials including:

Quartz
Borosilicate
BK7 or equivalent
Sapphire
And many more.

Depending on your application for the IR Cut Filter, we can help advise on the best achievable optic for your application. Our technical sales team are highly experienced with regards to IR Cut filters and know exactly how we can help with eradicating IR saturation at your sensor. Why not drop us line to see how we can help you.

All our wafers are fully inspected on their quality in our ISO 9001:2015 certified, state-of-the-art Metrology laboratory, using our Starrett AV300 Video Imaging Device for dimensions. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components.
