Abstract
Provided are a spectrometer capable of more effectively reducing stray light and an incident light limiting member to be used for the spectrometer. At least a part of light not entering an effective area of a diffraction grating is blocked by being reflected by a mask plate provided between an incidence plate and the diffraction grating. Further, the light reflected by the mask plate is attenuated in a trap space. Thus, the light blocked by the mask plate does not reach the diffraction grating side and does not function as a stray light source, so that stray light can be more effectively reduced.
