摘要： A microlens array of high converging efficiency is provided, independently of the array and lens filling rate of microlens arrays, with a method of manufacturing microlens arrays using the diffusion process. A multitude of refractive-index distribution type microlenses formed by diffusing in a planar transparent substrate a substance contributing to increasing the refractive index of the substrate are two-dimensionally and regularly arranged on the surface of the substrate. The microlenses are densely arranged on the surface of the substrate, and diffusion fronts of the microlenses form regions where the diffusion fronts are fused with those of the adjoining microlenses. The length of a region where certain two adjoining microlenses are fused together, in the direction of a straight line connecting the centers of the two microlenses is less than 20% of the array pitch of the microlenses in the above-mentioned direction.

摘要： A light detection device for detecting an optical path position of invisible light. The detection device includes a main body and a light guide. The light guide includes a distal end functioning as a light incident portion through which the detected light enters and a light radiation portion from which visible light is emitted. A drive mechanism reciprocates the light guide in an X-direction while vibrating the light guide in a perpendicular Y-direction. The distal end of the light guide rod moves within a light detection area in an XY plane. A visible light-emitting unit radiates visible light from the distal end when the detected light enters the distal end. The visible light-emitting unit includes a photo-detector for detecting the detected light and a light-emitting element for generating the visible light when the photo-detector detects the detected light.

摘要： The improved illuminating comprises a spheroidal mirror, a light source, a spherical mirror and a condenser lens. The spheroidal mirror has such a shape that it is deficient of a portion that would otherwise reflect light that illuminates any portions other than the object to be illuminated, and that the light from the light source which is directed toward said missing portion is reflected by the spherical mirror positioned on the rear side of said missing portion as seen from the light source and makes another reflection by that part of the spheroidal mirror which faces away said missing portion, thereby illuminating the object. The light source is positioned at the first focal point of the spheroidal mirror in such a way that it faces the mirror, and the spherical mirror is positioned in such a way that its reflecting face lies at the second focal point of the spheroidal mirror. An open window for the exit of light beams is provided in the spherical mirror at a position near the second focal point of the spheroidal mirror, and the condenser lens is provided further ahead of the open window (closer to the object to be illuminated).

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： An optical module includes a package, which accommodates an optical system. A package main body has an opening. A lid is attached to the main body to close the opening of the main body. The lid seals the package. An anti-deterioration agent for preventing deterioration of the optical system is located inside the package at a position out of a light path of the optical system. The anti-deterioration agent includes at least one of desiccant and deoxidant.

摘要： In a small-sized optical module, opposite side surfaces of a collimator lens (2) and opposite side surfaces of a polarization compensating filter (5) are fixed to opposite side surfaces of a rectangular frame (4). Two open surfaces are provided in the rectangular frame (4), so that optical components can be finely adjusted easily, and a large number of small-sized optical components can be aligned and assembled accurately. Reinforcing members (6) are provided in the open surfaces of the rectangular frame (4) so that the shape of the rectangular frame (4) can be retained against external force. After a diffraction grating (3) is fixed to the reinforcing members (6), the reinforcing members (6) with the diffraction grating (3) are adjusted, aligned and fixed to the rectangular frame (4).
