Title SPECTROMETRY DEVICE
Abstract This spectrometry device 200 comprises: a fixed reflection member 21 that has a fixed reflection surface 21a; a movable reflection member 22 that has a movable reflection surface 22a and that is disposed in parallel to and side-by-side with the fixed reflection surface 21a; a drive mechanism 23 that drives the movable reflection member 21 to reciprocate in the normal direction of the fixed reflection surface 21a; a guiding optical system that guides measurement light emitted from a measurement object so that such light extends across the fixed reflection surface 21a and the movable reflection surface 22a; an image forming optical system that causes light resulting from the measurement light guided to the fixed reflection surface 21a being reflected by the fixed reflection surface 21a and light resulting from the measurement light guided to the movable reflection surface 22a being reflected by the movable reflection surface 22a to respectively condense on an image forming surface; a photodetector 40 that detects the intensity of the light which has condensed on the image forming surface; through holes 22c, 22d that are formed in the movable reflection member 22 in parallel to the reflection surface 22a; and indicators 21d, 21e that are formed on the fixed reflection member 21 and that are provided at positions so as to be visible from the through holes 22c, 22d.
Outline of related art and contending technology Background Art
One technique for measuring spectral characteristics is referred to as imaging type 2 dimensional Fourier spectroscopy). In this method, non-directional light (emitted from the sample surface (object surface) is converted into parallel luminous flux by an objective lens, And a phase shifter composed of a fixed mirror part and a movable mirror part arranged in parallel with each other and side by side, and the measuring light (reflected by both mirror parts is condensed at the same point on an imaging surface by an imaging lens. The movable mirror part is moved to impart an optical path length difference between the measurement light reflected by the fixed mirror part and the measurement light reflected by the movable mirror part, so that the measurement light condensed on the imaging surface interferes with each other to form interference light of the measurement light. Detecting the intensity of this interfering light at each element of a 2 dimensional array device, such as a 0 0 0 camera, disposed on the imaging plane; A set indicating the intensity change of the interference light according to the optical path length difference is obtained, and a spectral characteristic (spectrum) of the measurement light is obtained by mathematically Fourier transforming the set.
