Short-wave Pass Filters: Infrared

Infrared Short-wave Pass (IR SWP) Filters transmit wavelengths shorter than their specified 5% cut-off wavelength and block longer wavelengths. Stock filters are optimized for collimated input at normal incidence and ambient temperature (0° AOI, f/inf, 298K). Out-of-band (OOB) transmission levels are <=0.1% average and <=1% maximum in the cited blocking range. Custom infrared short-wave pass filters can be designed, manufactured, and verified to meet almost any spectral and/or system operating requirement upon request.

To assist you in choosing your infrared short-wave pass (IR SWP) filter, visit our product selector to choose a SWP filter based on your desired thickness, blocking, and other qualities.  If you still don’t find what you’re looking for then let us create it for you, we offer custom solutions for your unique applications. If you have questions, we welcome you to contact us.  Reynard Corporation’s optical engineers can also assist you with your quote.
