Abstract: A spectrometer comprises a package having a stem and a cap, an optical unit arranged on the stem, and a lead pin penetrating through the stem. The optical unit has a dispersive part for dispersing and reflecting light entering from a light entrance part of the cap, a light detection element for detecting the light dispersed and reflected by the dispersive part, a support for supporting the light detection element such as to form a space between the dispersive part and the light detection element, a projection projecting from the support, and a wiring electrically connected to the light detection element. The projection is arranged at such a position as to be in contact with the stem. The lead pin is electrically connected to a second terminal part of the wiring arranged in the projection.

Abstract: A spectrometer may include: an input configured to receive optical radiation; a dispersion element configured to disperse by wavelength the optical radiation passing from the input; an output; and/or a spatial light modulator (SLM) configured to receive a wavelength region of the optical radiation dispersed by the dispersion element, and configured to selectively direct wavelength portions of the received wavelength region to the output. The input may be configured to provide a plurality of entrance field stops by which the dispersion element is, in use, illuminated. Each of the plurality of entrance field stops may cooperate with the dispersion element to generate a different dispersed wavelength region at the SLM.
