For excellent visible range transmission and a proven ability to block unwanted UV and NIR light, Knight Optical’s custom IR-cut filters offer superior performance with sharp transitions between bands. Widely used in CMOS and CCD detector systems, as well as a host of other applications, the transmission of these filters is readily improved with the addition of an anti-reflective coating, particularly useful for precision grade applications.
Because they are custom made, all our IR-cut filters can be supplied in any size, shape or thickness and a range of transmission wavelengths. Short lead times are no issue, so if your project is time-sensitive, you can rely on our team to deliver on time and strictly to specification. We can also work within a range of budgets. Complex requirements never prove an issue for our experts.
Our IR-cut filters are available in standard 5mm, 10mm, 12.5mm, 15mm, 25mm and 50mm diameter or square types. We are happy to cut and edge filters for non-standard sizes to suit your application.
