320nm UV Interference Bandpass Filter 12.5mmdia x 10nmBW
|Avg. Blocking OD||4|
|Avg. Blocking Range||200nm to 1150nm|
|Peak Transmission (%)||30|
Our mounted range UV interference filters are used to isolate and transmit a specified narrow wavelength and reflect all other incident wavelengths in the ultra-violet and visible spectrum.
These high-quality ultraviolet interference bandpass filters are available from 214nm-320nm in various bandwidths to meet a range of UV instrument requirements such as fluorescence imaging and UV sterilisation applications.
Typically, our mounted filters are 3-7 cavity and in most cases, blocking is metal dielectric from 200nm to FIR (3000+nm) at OD4.
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.
Knight Optical can provide custom dimensions to above 100mm, please contact our sales team 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.
