Abstract

PURPOSE:To minimize long cycle of noise by introducing only a transmitted light near the center of a sample container into a spectroscope through a reduced image thereof formed at an incidence slit with a wide irradiation thereof in a magnified image of a filament of a light source. CONSTITUTION:A tungsten lamp 1 has a longitudinal filament 8. A white light generated from the filament 8 enters a lens 2 to be condensed at the center of a test tube 3. An image of the filament 8 forms magnified at the center of the test tube 3. A light flux enters an incidence slit 5 in the range corresponding to the center of the test tube 3. The white light entering through the incidence slit 5 reflects at a convex grating 6 while diffracting whereby a spectrum is provided in a photodetector 7.
