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.

Abstract: A spectrometer includes a light detection element having a substrate made of a semiconductor material, a light passing part provided in the substrate, and a light detection part put in the substrate, a support having a base wall part opposing the light detection element, and side wall parts integrally formed with the base wall part, the light detection element being fixed to the side wall parts, the support being provided with a wiring electrically connected to the light detection part, and a dispersive part provided on a surface of the base wall part on a side of a space. An end part of the wiring is connected to a terminal of die light detection element. An end part of the wiring is positioned on a surface in the base wall part on an opposite side from the side of the space.

Abstract: A SERS unit comprises an integrally formed handling board and a SERS element secured within a container space provided in the handling board so as to open to one side in a thickness direction of the handling board. The SERS element has a substrate arranged on an inner surface of the container space and an optical function part formed on the substrate, for generating surface-enhanced Raman scattering.

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.

Abstract: A surface-enhanced Raman scattering element comprises a substrate having a principal surface; a molded layer having a support part formed on the principal surface of the substrate so as to extend along the principal surface and a fine structure part formed on the support part; a frame part formed on the principal surface of the substrate so as to surround the support part and fine structure part along the principal surface; and a conductor layer formed on at least the fine structure part and constituting an optical functional part for generating surface-enhanced Raman scattering; while the fine structure part are formed integrally with the support part.

Abstract: An optical element includes a base having a curved depression formed in a front surface thereof and a formed layer arranged on the base. The formed layer includes a main part in the depression as viewed from a depth direction of the depression and an overhang on the front surface of the base while connecting to the main part. An opposite surface of the main part to a surface thereof on a side of an inner surface of the depression is formed like a concave curve that is concave in a same direction as the inner surface of the depression. A predetermined surface of the main part that is opposed to the inner surface of the depression is provided with an optical function part.
