A bandpass filter is a filter that only passes the light source in the required band. Normally, the narrower the band, the lower the transmittance, but with this product it is possible to obtain high transmittance.
Bandpass filters are available in a wide range from 310 to 1,550nm. Narrowband products range from FWHM=0.5nm to wideband products, and customization is also available.
