[0003] Spectral luminometers for measuring and evaluating spectral luminances, luminances and colors of various light sources and display devices have been conventionally widely used (for example, see Japanese Unexamined Patent Publication No. H6-74823). FIG. 18 is a diagram showing a construction of a light splitting unit in a prior art spectral luminometer. As shown in FIG. 18, a light splitting unit 310 built in the prior art spectral luminometer is the so-called polychrometer in which an incident beam through an incident slit 311 is dispersed by a diffraction grating 313, and a dispersed image of the incident slit 311 is formed on a light receiving sensor array 314 by a imaging optical system 312. This polychrometer simultaneously measures an intensity distribution of all the wavelengths in a measurement range. FIG. 19 is a graph showing spectral sensitivities of light receiving sensors S.sub.n (n=0 to 60) of the light receiving sensor array 314 of the polychrometer. The polychrometer shown in FIG. 19 has a half-width of 10 nm, and an interval between the sensors is 5 nm, and a wavelength range is from 400 to 700 nm. In FIG. 19, horizontal axis represents wavelength and vertical axis represents relative sensitivity. FIG. 19 shows only the relative sensitivities of the light receiving sensors S.sub.0, S.sub.1, S.sub.2, S.sub.30, S.sub.58, S.sub.59, S.sub.60.
