A spectroscopic detector (110) includes a spectroscopic element (11) for dispersing light, a photodetector (12) for detecting the light dispersed by the spectroscopic element and a condensing optical system (13) for condensing the dispersed light to the photodetector and compensating for a deviation in a detected wavelength deriving from nonlinearity of the angle of emergence generated in the spectroscopic element through chromatic aberration of magnification. |
