IPC: G01J3/50
Filed: 1989-05-12
Abstract: PURPOSE:To accomplish the direct observation and the color identification of a substance to be detected by irradiating the substance to be detected with light beams in two different wavelength bands and measuring and comparing the reflected light beams. CONSTITUTION:Interference filters 2 and 3 which allow the light beam to pass only specified wavelength bands different from each other and 1st and 2nd optical systems obtained by combining lenses 4 and 5 with the filters 2 and 3 are provided. The substance to be detected 1 is irradiated with white light and the reflected light thereform is received by both optical systems.

Since a level difference is caused by the difference of spectral reflectance which differs according to the wavelength between both quantities of reflected light, the output of the subtracter 8 becomes A-B. Thus, the color of the substance to be detected 1 is identified with the direct observation without working the substance to be detected 1.
