摘要： A light measuring device is designed, so that excitation light, emitted by a light source, is guided through an excitation light optical fiber to irradiate a sample, and that fluorescence discharged by the sample is guided to an optical detection system through a receiving light optical fiber. A coupling lens is arranged ahead of the excitation light optical fiber and ahead of the receiving light optical fiber on the sample side. A sample container for retaining a sample is so designed that a lens portion, for collecting excitation light and fluorescence, is integrally formed with the cylindrical bottom. According to this arrangement, excitation light is changed to parallel light or converged light by the coupling lens, and is collected at the sample by the lens portion integrally formed with the bottom of the sample container.

摘要： It is a collimator adapted to convert divergent light beams outputted from an optical fiber bundle to parallel light beams through a collimator lens. A large diameter optical fiber is disposed between an optical fiber bundle, which is a bundle of a large number of multimode optical fibers and serves as one optical transmission path, and a collimator lens. A cross-section of the core of the large diameter optical fiber is larger than a range in which the cores of the optical fibers of the optical fiber bundle are present. Also, a group of divergent light beams outputted from the optical fibers of the optical fiber bundle is converted by the large diameter optical fiber to one light beam.

摘要： A diffraction optical element including an element body having a large number of grooves formed on its surface to form a grating, and a grating shape adjusting layer deposited on a grating surface of the element body by oblique incidence or material particles onto the grating surface, wherein the grating shape adjusting layer per se is made of a reflecting film material. By the grating shape adjusting layer, the contour shape of the resulting grating surface in a section perpendicular to a lengthwise direction of the grooves is made not similar to the sectional shape of the element body. A reflecting film may be formed on a grating shape adjusting layer made of another material. A reflecting film may be provided on the element body before a grating shape adjusting layer made of a transparent dielectric material is provided on the reflecting film.

摘要： An optical module according to the invention includes an optical fiber, a planar lens, and a flat plate-like transparent member for optically coupling the optical fiber and the planar lens to each other. The transparent member has a nearly spherical concave portion formed in a surface of the transparent member. An end surface of the optical fiber is inserted into the concave portion of the transparent member so as to abut thereon and bonded and fixed thereinto. Further, a surface of the transparent member opposite to the surface in which the concave portion is formed is joined to a surface of the planar lens to make an optical axis of the optical fiber coincident with an optical axis of the planar lens. The concave portion is filled with a filler material having a refractive index higher than that of the transparent member to thereby fix the optical fiber.
