Band-pass optical filter

narrow-bandinterference

This range of UV type interference band-pass filters are used to isolate and transmit a specified narrow wavelength and reflect all other incident wavelengths in the ultra-violet spectrum. Knight Opitcal’s standard stock range of high quality ultra-violet interference bandpass filters is available from 214nm-320nm in various bandwidths to meet a range of UV instrument requirements, such as fluorescence imaging and instrumentation. This range of UV bandpass filter has high transmission at very competitive costs. Typically, our filters are 3-7 cavity and in most cases blocking is metal dielectric from 200nm to FIR (3000+nm) at OD4. We can also supply interference bandpass filters with dielectric blocking on request. The individual filters are CNC scribed and hermetically sealed to form a stack in their rings, ensuring maximum long-term stability. Although our standard stock range is mounted, un-mounted types with aerospace paint blackened edges can be supplied at request. All our interference bandpass filters are supplied with a transmission curve; ASCI files are available on request.
