Knight Optical (UK) Ltd 405nm Narrowband Interference Bandpass Filter 25mmdia x 3nmBW 405FIN25

This range of interference band-pass filters are used to isolate and transmit a specified narrow wavelength and reflect all other incident wavelengths in the spectrum 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.
