Title:
SPECTROSCOPIC MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/220531
Kind Code:
A1
Abstract:
A spectroscopic measurement device according to an aspect of the present invention comprises: a housing (1) forming an exterior; a base plate (3) that is fixed to the housing at a predetermined interval above a bottom plate (1a) of the housing in the housing; a spectroscopic detection unit (6) which includes a diffraction grating that disperses the wavelength of light to be measured, a detection unit that detects the light of which the wavelength is dispersed by the diffraction grating, and an optical system that introduces, to the diffraction grating, the light to be measured and/or guides, to the detection unit, the light of which the wavelength is dispersed by the diffraction grating, and in which the diffraction grating, the detection unit, and the optical system are fixed to an optical system base plate (6a); a plurality of vibration absorption units (7) that fix the optical system base plate to the base plate while having a vibration absorption action; and an electric circuit unit (5) that includes at least an electric circuit for receiving output from the detection unit and is disposed in a space between the bottom plate and the base plate. Accordingly, provided is a spectroscopic measurement device that has excellent vibration resistance and impact resistance and has a small size, thereby achieving excellent space saving.
