Laser Line

Iridian’s laser line filters are amongst the best in the world featuring high transmittance (greater than 90% in the pass band); narrow bandwidth (1-3 nm) and excellent blocking from 300 to 1200 nm. Iridian’s laser line filters are optimized to reduce the spectral noise of a laser source and pass only the desired laser wavelength through a steep transition from pass band to deep blocking.

Iridian’s standard laser line filters have full width, half-maximum (FWHM) bandwidths varying from 1-3 nm and better than OD 3 blocking from 300 to 1200 nm outside the passband wavelength region.

Custom Laser Line Filters

In addition to the standard Laser Line filters, Iridian can custom manufacture a laser line filter to your specification (laser wavelength, desired FWHM, angle of incidence, polarization, blocking range).
