Model :LS-Broadband BandPass Filter Appearance Standard: US Military Standard 60-40 Introduction: Bandpass filter, it is a type of filter that allows light within a certain range of bands to pass through while blocking light on both sides of the passband. Bandpass filters are classified by wavelength into ultraviolet bandpass, visible light bandpass, near-infrared bandpass and far-infrared bandpass, etc. They play a role in eliminating excessive background noise and enhancing the signal-to-quality ratio in fluorescence imaging and life science detection systems, and have a very wide range of applications.
