Wafers for substrates for IR Cut Off Filters Verified by Europages badge

Our wafers are produced as thin as 500μm & provide exceptional surface quality

Description

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 wafers are produced as thin as 500μm & 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. Please read PDF for full specification
