Claim 0:
1. A spectroscopic detector assembly, comprising:
a first housing;
a second housing;
a camera lens housed in the first housing; and
an image sensor housed in the second housing,
the first housing having a first through hole formed therein,
the second housing having a second through hole formed therein,
the second housing being attached to the first housing so as to allow for communication between an inside of the second housing and an inside of the first housing via the first through hole and the second through hole,
in a state where the second housing is attached to the first housing, a periphery of the second through hole being located inside a periphery of the first through hole,
the camera lens having an incidence end and an emission end in a direction of an optical axis of the camera lens, the emission end being an end opposite to the incidence end,
the emission end being inserted in the first through hole,
a difference between an outer diameter of the camera lens at the emission end and an inner diameter of the first through hole being smaller than a thickness of the first housing at a portion where the first through hole is formed,
the image sensor facing the emission end in the direction of an optical axis of the camera lens, with a space inbetween.
