Method and standard filter method. The commonly used transmittance standard solution is a potassium dichromate acidic solution of perchloric acid. It must also be prepared and used according to the specified conditions when using a transmittance standard solution. This will ensure the absorbance standard value. Since the currently available transmittance standard filters are mostly in the visible range, - is used in the visible light region, and the potassium dichromate standard solution method is mainly used in the ultraviolet region. For the visible light region, the nominal values â€‹â€‹of the transmittance are 10%, 20%, 30%3 slice spectral neutral filter, determined at 440nm, 546nm, 635nm;The specific operation is: using air as a reference, the filter is placed in the absorption cell frame at one time, and the transmittance of the transmittance standard is measured at each of the above fixed wavelengths 3 Times, record the transmittance of each 3 measurement, and calculate the transmittance accuracy and repeatability of the instrument. The difference between the average value of the 3 measurement and the standard value is the transmittance accuracy; the difference between the maximum value and the maximum value of the 3 measurement is the transmittance repeatability.
