Knight Optical (UK) Ltd 220nm UV Interference Bandpass Filter 12.5mmdia x 14nmBW 220FIB12

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. These high quality ultra-violet interference bandpass filters are 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. 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; ASCII files are available on request. Filters are available on short lead times directly from stock, or as custom products designed to fit your specific application.
