Claim Text:
1. A microscope spectrometer in which, when an excitation light from a light source illuminates a sample, a light emitted from the sample that enters a microscope is analyzed, the microscope spectrometer comprising: a first optical means that forms the light emitted from the sample as a parallel beam; a first variable bandpass filter means of incident light angle tuned type having a variable wavelength passband that transmits incident light which, of the parallel beam of incident light, is light of a pre-established wavelength passband; a second variable bandpass filter means of incident light angle tuned type having a variable wavelength passband that transmits incident light which, of the light incident from the first variable bandpass filter means, is light of a pre-established wavelength passband; an optical axis adjustment means that is composed of an optical plate that transmits light and corrects the position shift of the optical axis of the scattered light in a two-dimensional plane that is caused by the first variable bandpass filter means and the second variable bandpass filter means; a two-dimensional array light detection means that images the light in the wavelength passband; and a control means that controls the timing of the imaging by the two-dimensional array light detection means and controls the first variable bandpass filter means and the second variable bandpass filter means to change, in accordance with the timing, the wavelength passband of the first variable bandpass filter means and the second variable bandpass filter means, the control means further controlling the optical axis adjustment means, wherein the control means controls the timing of the imaging by the two-dimensional array light detection means to turn ON imaging at a time the control means controls the first variable bandpass filter means and the second variable bandpass filter means to change the pre-established wavelength passband to a changed wavelength passband for each of the first variable bandpass filter means and the second variable bandpass filter means, and to turn OFF the imaging by the two-dimensional array light detection means before an end of time each of the first variable bandpass filter means and the second variable bandpass filter means is transmitting the incident light at the changed wavelength passband, and wherein the first optical means, the first variable bandpass filter, the second variable bandpass filter, and the two-dimensional array light detection means are disposed to have a common optical axis in an unbranched straight line.
