Claims

[Scope of utility model registration request]

In a spectrophotometer that measures the spectral transmittance or reflectance of substances, a spare light bulb is placed in the light source chamber or close to the light source bulb, and a detector is installed in a part of the light source chamber to detect whether the light source bulb is disconnected or the brightness is low. A spectrophotometer is characterized in that the operation of the spectrophotometer is temporarily interrupted upon detecting that the light has decreased, the operation of the spectrophotometer is temporarily interrupted, the operation is switched to a spare bulb, the lighting of the bulb is confirmed, and the operation of the spectrophotometer is continued.
