Band-pass optical filter

interferencelaser

Interference filters pass light of a narrow bandwidth and a given wavelength and reflect or block all other light. Our Laser line filters are specifically designed for common laser-line wavelengths with standard 10nm FWHM type from 350-1550nm, and selected 3nm and 1nm FWHM for popular laser lines such as HeCd, Nd:Yag, HeNe, Diode, Krypton, Ruby, XeF. Knight Opitcal’s range of laser line interference filters have excellent out of band blocking better than OD4 with high transmission characteristics making them perfect for high demanding laser based spectrometer instrumentation applications.
