Notch Filter

Asahi Notch Filter perfectly blocks the specific wavelength of laser-line with an optical density >OD6 and keep high transmission(ave)>90% outside the laser wavelength. Asahi Notch Filters will allow professional scientists to measure Stokes and Anti-Stokes simultaneously. PDF brochure
