                            Narrow Bandpass Filter
                        

                        

                        

                            The surface of glass and other substrates is coated with a narrow band-pass film system in the near-infrared band to achieve high transmission of incident light in specific bands and deep cut-off in other bands. It has the characteristics of high recognition accuracy, strong anti-interference ability and large recognition range.
