Which is good infrared filter factory in Shenzhen Features: Compared with traditional colored glass filters, I produced a short pass and long wave pass filter with a cutoff steepness large, high transmittance and optical density of the background big advantage, but also with the traditional method of optical glass completely different point, when the incident angle change (rotate from 0 degrees to a wide angle), characterized by a cutoff wavelength will shift to shorter wavelength. This function can be used to fine-tune aspects of the system, and be able to get your desired wavelength. Applications: beauty equipment, police multiband detection equipment, flashlights, lighting color film, face recognition time attendance, optical instruments, fiber optic lighting, gold halogen insulation sheet, cold light display cabinets. Optical indicators: Through bands: 425nm-1100nm minimum transmittance: T> 94% center wavelength: 420nm ± 3 cutoff wavelength: 350nm-405nm cutoff depth: T <0.1% filter, the preferred macro photoelectric satisfied! Shenzhen Optoelectronic Technology Co., Ltd. is satisfied that the macro | infrared filter factory in Shenzhen Which is good
