317nm Narrow Band Pass Filter
The 317nm narrow-band filter is used to take out ultraviolet light from white light or take out the required ultraviolet light from multi wavelength light.
317nm narrow-band filter is used in fluorescence observation when ultraviolet light irradiation is required but visible light irradiation is not required. It can also be used to remove the i-wire (365nm) of the mercury lamp.
By inserting a filter into the detector in the short wavelength spectrum region, the visible light with high brightness can be blocked and the sensitivity in the ultraviolet wavelength spectrum region can be improved.
