Abstract
The present invention has the object of preventing saturation of an optical detector by applying an inverted bias voltage so as to allow accurate measurement of optical spectra. In order to achieve this object, the present invention provides voltage applying means 8 controlled by a control section 6 for applying an inverted bias voltage to the optical detector 3 in order to prevent saturation of the optical detector 3.
