550nm Narrow Band Filter
550nm narrow band filter adopts all dielectric coating technology to achieve all optical properties. The optical properties are independent of the substrate thickness, so the thickness can be very thin, so it can be built into the camera. Because the absorption type color glass is not used as the substrate, the filter has good stability and is not easy to mildew or fog.
The products are applied to 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 instruments, infrared ink recognition, red film recognition, face recognition sensor system, handheld infrared laser rangefinder, laser rangefinder, optical instruments, medical and health equipment and testing instruments.
