Product features:

Compared with the traditional colored optical glass filters, my company production of short wave and long wave pass filter with cutoff steepness of large, high transmittance and background light density advantage, but also with the traditional optical glass method completely different point, when the incident angle changes ( from 0 degrees to large rotation angle ), features cutoff wavelength will shift to short wavelength direction. This function can be used in system fine-tuning, and you can get the desired wavelength.

Application fields:

Beauty apparatus, police multi-band detection apparatus, flashlight, stage lighting and color temperature orange, face recognition attendance equipment, optical instruments, optical fiber lighting, gold halogen lamp heat insulation sheet, cold light display cabinet.
