Abstract
Provided is a spectrophotometer having a sample container, a light-source unitfor casting measurement light into the sample container, a photodetectorfor detecting light obtained from the sample containerilluminated with the measurement light, a light separatorplaced between the light-source unitand the sample container, an A/D converterfor converting detection signals from the photodetectorinto digital signals, and an A/D conversion time controllerfor controlling an A/D conversion time in the A/D converter. The A/D converterreceives, for each A/D conversion time, detection signals sequentially produced by the photodetector, and sequentially outputs values corresponding to the amounts of signals received. The A/D conversion time controllercontrols the A/D conversion time at five times (preferably, ten times) the cycle of commercial power supplies or longer during wavelength-correctness validation of the light separator
