490nm shortwave pass filter

This 490nm short wave pass has its unique optical index. After passing through the filter, only the blue spectrum will pass through. Through the application of this optical characteristic, such as the multi band detector for police, one of the optical devices will be used. As well as beauty instruments, police multi band detection instruments, strong light flashlight, stage light color film, face recognition attendance meter, optical instruments, optical fiber lighting, gold halogen lamp heat insulation sheet, cold light source display cabinet.
