550nm shortwave pass filter
Compared with the traditional colored optical glass filter, the 550nm short wave pass filter and the long wave pass filter produced by our company have the advantages of large cut-off steepness, high transmittance and high background optical density, and are completely different from the traditional optical glass method. When the incident angle changes (turning from 0 ° to a large angle), the characteristic cut-off wavelength will move towards the short wave direction. It is used for beauty instruments, police multi band detection instruments, strong light flashlight, stage light color film, face recognition attendance instrument, optical instruments, optical fiber lighting, gold halogen lamp heat insulation sheet, cold light source display cabinet.
