Optical Interference Bandpass Filters
High Performance Thin Film Optical Filters
Knight Optical's optical interference bandpass filters transmit a precise wavelength while blocking unwanted light.
Stock Interference Filters from 214-2000nm
With 3nm narrowband widths to 100nm broadband optical filters availble, which are hermetically sealed and CNC-scribed for long-term stability.
Laser line, Fluorescence, and Imaging Applications
Stock filters provide a cost effective solution for prototyping.
Custom Optical Interference Filters Available
If our stock optical interference bandpass filters do not meet your requirements, bespoke designs are available upon request.
