Abstract: A spectrophotometer 10 includes built-in detector 24 and external detector 32. When a mountable/removable optical path switcher 23a is installed in a specimen chamber 23, measurement based on detection signals from built-in detector 24 is replaced by measurement based on detection signals from external detector 32. The spectrophotometer further includes a measurement data threshold-value storage unit 51 that stores threshold value T for measurement data from built-in detector 24 or external detector 32, and a light-receiving detector recognition unit 52 that recognizes which detector is able to receive the measuring light beam based on the results of a comparison between threshold value T and measurement data from built-in detector 24 or external detector 32 while the measuring light beam is being introduced into specimen chamber 23.
