Abstract
A spectrometerA is made up of: an optical bodywithin which a light separation path is set along which an object light to be separated propagates; a light entry slitthrough which the object light enters; a diffraction gratingfor spectrally separating the incident object light; and a photodiode arrayfor detecting the object light separated by the diffraction grating. As an optical member for optically interconnecting the optical bodyand the photodiode array, an optical connection memberis provided, with its light entry surfacefor the separated object light in contact with the upper surfaceof the optical body, with its light exit surfacein contact with the photodiode array, with the light exit surfacetilted by a specified angle relative to the light entry surface. Thus, the spectrometer capable of bringing about sufficient accuracy of placing optical elements in a simple constitution while bringing down cost is realized.
