  • Publication number: 20190056267
    Abstract: A spectrometer includes a support having a bottom wall part in which a depression including a concave curved inner surface and a peripheral part adjacent to the depression are provided, and a side wall part disposed on a side on which the depression is open with respect to the bottom wall part, a light detection element supported by the side wall part while opposing the depression, and a dispersive part disposed on the inner surface of the depression. A length of the depression in a second direction in which a plurality of grating grooves included in the dispersive part is aligned is larger than a length of the depression in a third direction orthogonal to the second direction when viewed in a first direction in which the depression and the light detection element oppose each other. An area of the peripheral part adjacent to the depression in the second direction is larger than an area of the peripheral part adjacent to the depression in the third direction when viewed in the first direction.

  • Patent number: 10184834
    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.

  • Publication number: 20180216997
    Abstract: A spectrometer includes a support having a bottom wall part in which a depression is provided and a side wall part, a light detection element supported by the side wall part while opposing the depression, a resin layer disposed at least on an inner surface of the depression, and a dispersive part provided in the resin layer on the inner surface of the depression. The resin layer is in contact with an inner surface of the side wall part. A thickness of the resin layer in a first direction in which the depression and the light detection element oppose each other is larger in a part in contact with the inner surface of the side wall part than in a part disposed on the inner surface of the depression.
