Abstract

PURPOSE:To make quick and correct for the setting of test piece, by making bright the colorimetric center with spot radiation. CONSTITUTION:The upper part of the integrating sphere 1 is provided with the half mirror 9, monochromatic radiation lamp 10, light convergence lens 11, and monochromatic filter 12. Thus, while light is radiated on the integrating sphere 1 from the white light source 2 to emit the test piece 4 on the test piece stand 3 with diffused light. A given part of the scattered reflection light from the surface enters the inlet slit 6 of the spectrum unit with the lens 5, it is scattered each wave length with the diffraction grating 7, and the reflection spectrum is recorded by being fed to the detectors 81 to 8n. When the test piece 4 is replaced, the test piece stand 3 is separated from the radiation window 1a of the integrating sphere 1. The monochromatic radiation projective lamp 10 is illuminated and the light is projected on the surface of the test piece 4 via the lens 11, monochromatic filter 12, half mirror 9, slit 6 and lens 5 as the monochromatic light spot making bright the center of colorimetric center of the test piece, to make easy the positioning of the test piece 4.
