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. For more information please contact our technical sales team with your requirements.
Please telephone our technical sales or email with your specification.
Dielectrically blocked filters are available for increased performance.
Stock filters can be supplied in pre-mounted threaded rings.
Other bespoke sizes to your specification either mounted or un-mounted.
Unmounted interference filters available, sealed around edges with high quality aerospace paint.
Small one-off or small batch quantity for new projects at very competitive prices and normally delivered within 6 weeks.
Alternative imperial sizes are available at short notice, normally within 1-2 weeks.
