    Abstract: A spectrometer for examining the spectrum of an optical emission source may include: an optical base body, a light entry aperture connected to the optical base body to couple light into the spectrometer, at least one dispersion element to receive the light as a beam of rays and generate a spectrum, and at least one detector for measuring the generated spectrum. A light path may run from the light entry aperture to the detector. A mirror group with at least two mirrors may be provided in a section of the light path between the light entry aperture and the at least one detector, in which the beam does not run parallel, which may compensate for temperature effects. In the mirror group, at least one mirror or the entire mirror group may be moveable relative to the optical base body and may be coupled to a temperature-controlled drive.

    Abstract: A linear frequency domain grating and a multiband spectrometer having the same. The linear frequency domain grating includes a dispersive optical element and a diffractive optical element being substantially in contact with the dispersive optical element or being substantially integrated with the dispersive optical element, configured to receive a beam of incident light along an incident optical path, and diffract and disperse it into its constituent spectrum of frequencies of the light that is output from the dispersive optical element along an output optical path, such that the output light has a spatial distribution on a focal plane in the output optical path that is a linear function of the frequency. The linear frequency domain grating is a transmissive-type grating or a reflective-type grating, depending on whether the incident optical path and the output optical path are in different sides or the same side of the diffractive optical element.

    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 separated from the stem. The lead pin is electrically connected to the second terminal part while being disposed to the projection.

    Abstract: An optical sensing module, adapted to sense a characteristic of an object by a sensing beam, comprises a carrying substrate, a transparent cover having a reflective surface thereon, a side wall, an optical grating, and an optical sensor. The reflective surface has a light-transmissive opening that exposes a part of the transparent cover. The side wall is disposed around the carrying substrate and is located between the carrying substrate and the transparent cover. The optical grating is disposed on the carrying substrate and a position of the optical grating corresponds to the light-transmissive opening. The optical sensor is disposed on the carrying substrate and is located at a side of the optical grating, wherein the carrying substrate, the side wall and the transparent cover form a vacuum chamber. The optical grating and the optical sensor are disposed in the vacuum chamber.
