625nm narrow band filter

625nm narrow-band filter with half bandwidth of 10nm is a very important optical component in optical applications and laser technology, especially in semiconductor lasers. In a certain band, there is only a small pass band with high transmittance in the middle, and there are high reflectivity cut-off bands on both sides of the pass band. This kind of narrow-band filter is collectively referred to as band-pass filter. The main function is to select the spectrum of light, so that the required light passes through and the light of unnecessary wavelength is cut off. At present, as an optical component for filtering and selecting spectral lines, band-pass filter has a wide range of applications.
