The 220nm ultraviolet narrowband filter, also known as the water quality detector filter, pure water detection filter, stray light filter, stray light standard substance detection filter, and ultraviolet transmittance standard filter, is a type of filter that only allows short wave ultraviolet light of about 220nm and 5nm to pass through. At present, it is widely used in water quality testing equipment. It should be noted that water quality testing involves two wavelengths: 220nm and 275nm. It is recommended to adjust to another wavelength after measuring the same wavelength of a group of samples, and then measure them uniformly. Do not measure the two absorbance values of one sample and then switch to another sample, as repeatedly adjusting the wavelength will cause certain measurement errors.
