IR Cut Filters
Our IR-Cut filters offer excellent visible range transmission while effectively blocking unwanted UV and NIR light. Our filters demonstrate sharp transitions between bands for superior performance.
Knight Optical are long term suppliers to the CMOS and CCD detector industries and our extensive range of custom options allow us to meet our customer’s demanding filter requirements. Our precision IR-Cut filters can be supplied in any size, shape or thickness and are often available on short lead times for time sensitive projects
. If required, our experienced team of technical sales staff can talk you through the custom process and ensure that your order is delivered on time and to specification.
We are also able to provide custom IR-Cut filters for general and precision applications with performance to suit your needs and budget. See below for a summary of our custom IR-Cut filter capabilties . The information presented here is not exhaustive so please get in touch if your exact specifications are not met.
For precision applications we strongly recommend using an anti-reflective coating
on the rear surface for improved transmission. Additionally, using a 20:10 scratch dig filter on a pre-polished substrate will help eliminate unwanted blotching in HD cameras.
Every component is individually tested by our skilled metrology technicians using our Cary 5000 spectrophotometer and top of the range UMA attachment to ensure all components meet our high quality standards. Full metrology reports can be supplied with each order where requested.
