405nm narrow band filter
405nm narrow-band filter adopts ion sputtered multilayer dielectric film, which has high environmental resistance and stability. Since no absorption filter is used, there are few temperature rise caused by absorption hot wire or element degradation caused by absorption of ultraviolet light, which can be used for various light sources
Main application fields of 405nm narrow-band filter: fluorescence analyzer, enzyme marker, cable TV upgrade equipment, wireless transmission equipment, mobile phone bar code scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical instrument, infrared ink recognition, red film recognition, face recognition sensor system. Hand held infrared laser rangefinder, laser rangefinder, optical instruments, medical and health equipment and testing instruments.
