Edge Pass, Long Edge Wide Angle Filter for Spectroscopic applications   

532 LPF Wide Angle   

Iridian Edge Pass filters are used to isolate one band of wavelengths from another by reflection or transmission. In Raman spectroscopy, edge pass filters are used to separate the excitation source wavelength from the emission wavelengths.

These circular filters offers superior performance for wider angle of incidence and cone half angles (CHA), with angle tuneable capability. They are typically used anywhere between 0° and 2°.
