LIGHT PROJECTING AND RECEIVING DEVICE FOR SPECTROSCOPIC ANALYZER

摘要

PROBLEM TO BE SOLVED: To reduce the load of a user relating to the maintenance of the light projecting and receiving surface of a light projecting and receiving device while making it possible to properly receiving the reflected light from a sample. SOLUTION: In a light projecting and receiving device for a spectroscopic analyzer, an irradiation guide means Gr for guiding the measuring light from a light source part 1 so as to pass the same through a light passing part 5 to irradiate a sample S and a light receiving guide means Ga for guiding the reflected light from the sample S entering from the light passing part 5 so that the reflected light is received by the light receiving part of the spectroscopic analyzer are provided in a dark box 3 equipped with the light passing part 5 permitting light to pass over the inside and outside. The irradiation guide means Gr guides measuring light so as to focus the same to the front position of the light passing part 5.
