PURPOSE: To obtain the multichannel spectrometer which measures reflection spectra at individual points in at least one linear area on a skin surface to be inspected without contacting.

CONSTITUTION: This multichannel spectrameter is equipped with an optical means equipped with lens systems 18, 21, and 22 which are directed to the skin surface and a white sight 17, a slot stop 19, and a diffraction grating 23 which is aligned with the slot of the stop behind the stop. On image planes (x) and (y) which are behind the diffraction grating and connected to an evaluation and display device 14, reflection spectra of individual dots in the linear area 25 that can determine the skin surface and white sight 17 are generated at the same time.
