PROBLEM TO BE SOLVED: To easily accommodate a light source, a diffraction grating and the optical axis of an ocular hole and facilitate spectral observation. SOLUTION: The spectroscope is obtained in that a diffraction grating is stuck on a slit at one end of a light shielding tube and a screen is attached behind so as to observe from an ocular hole at the backward.
