370nm narrow band filter
The 370nm narrow-band filter transmits a specific wavelength in the blue to green wavelength spectrum and cuts off the filters of other wavelengths in the visible light. It is used to take out blue light or green light from white light, or only take out light of specific wavelength from multi wavelength light.
It is equipped with various spectral widths and transmittance within the range of 370nm narrow-band filter, which can be used to take out spectral lines of specific wavelengths from various spectral line light sources. When inserting filter sheets in microscopes or cameras, it can sometimes improve the contrast of photography.
