Abstract
A spectrometer includes a package having a stem and a cap, an optical unit disposed on the stem, and a lead pin for securing the optical unit to the stem. The optical unit includes a dispersive part for dispersing and reflecting light entering from a light entrance part of the cap, a light detection element having a light detection part for detecting the light dispersed and reflected by the dispersive part, a support for supporting the light detection element such that a space is formed between the dispersive part and the light detection element, and a projection protruding from the support, the lead pin being secured to the projection. The optical unit is movable with respect to the stem in a contact part of the optical unit and the stem.
