    Abstract: A first optical system (10) according to the present disclosure includes a first lens (111) that guides light (LO) to a diffraction grating (3), a second lens (112) that collimates first diffracted light (L1) that was focused at a first focal point (f1), a pair of first mirrors (12, 13), a third lens (113) that focuses the first diffracted light (L1) at a second focal point (f2), and a fourth lens (114) that guides the first diffracted light (L1) that was focused by the third lens (113) to the diffraction grating (3). The first lens (111) and the fourth lens (114) have a substantially identical first focal length. The second lens (112) and the third lens (113) have a substantially identical second focal length. A first distance along an optical path from the first focal point (f1) to the second focal point (f2) is determined by a first predetermined condition.

    Abstract: A spectral sensor and a method for forming the spectral sensor is disclosed. The spectral sensor includes a planar waveguide on a substrate; a restriction mechanism that restricts a range of angles of incidence of light impinging onto the chirped input coupling grating; the chirped input grating formed to couple incident light into the planar waveguide, wherein the chirped input coupling grating comprises a first transverse chirp to provide a spectrally selective coupling of incident light Into the planar waveguide; a propagation region to filter out light that is not coupled into the planar waveguide; a detector array arranged on the opposite side of the propagation region from the chirped input coupling S grating to receive light coupled out of the planar waveguide and produce output signals representative of the light; and an electrical circuit to readout output signals from the detector array.

    Abstract: An automatic analysis apparatus comprises: a light source generating light having a center wavelength equal to or shorter than 340 nm; a fluorescent substance excited by the light source light, and generates light together with transmitted light from the light source, having a wavelength of 340 nm to 800 nm; a condenser lens; at least one slit; a reaction cell holding a reaction solution where a specimen and reagent are mixed, and that the light source light and the light from the fluorescent substance enter; and a detector that detects light transmitted through the reaction cell. The light source, fluorescent substance, condenser lens, and slit are provided along a straight light corresponding to the optical axis. The width of the slit's opening is equal to or narrower than the width of a ray forming an image of the light source at the position of the slit.
