摘要： A microplate reader includes a light emitting portion for irradiating each of a plurality of test samples with excitation light, a light receiving portion for receiving return light from each of the test samples, and an XY stage for moving the light emitting portion and the light receiving portion to traverse and scan the test samples. The light emitting portion and the light receiving portion are defined at the same location on a reflection surface, which is formed on a distal end of a glass light guide rod. The light emitting portion irradiates each test sample with a sufficient amount of excitation light so that a sufficient amount of return light enters the light receiving portion.

摘要： In the light-receiving element array device according to the present invention, a light-receiving section can be arranged at a position close to an input optical fiber so that the light-receiving element array device can be used as an optical demultiplexer based on the Littrow arrangement. Further the present invention enables suppression of coma aberration and minimization of an optical demultiplexer by shortening a length of the optical system. To achieve the above-described object, a rectangular chip having a light-receiving section with a number of light-receiving elements arrayed in row thereon is sealed in a rectangular package having external leads and the bonding pads on the chip and the bonding terminals of the packages are connected with a bonding wire or the like. This light-receiving element array device has any of the following constructions: (1) in which no bonding pad is provided along one longer edge of the chip in an area around a light-receiving section of the chip, (2) in which no bonding terminal is provided along one longer edge of the package, or (3) in which no external lead is provided along one longer edge of the package, or a combination of the constructions, and the chip is accommodated in the package at a position displaced to one side of the package.

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： The improved illuminating apparatus 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 process for producing a low-loss embedded waveguide is disclosed, which comprises: a first ion exchange step in which a glass substrate containing a monovalent ion and capable of undergoing ion exchange is subjected to thermal ion exchange through an ion exchange-control film provided on the substrate and having a predetermined waveguide pattern formed therein, by immersing the substrate in a first molten salt containing a first monovalent ion capable of changing the refractive index of the substrate; an etching step in which the ion exchange-control film is removed form the substrate by etching; an electric field-applying annealing step in which an electric field is applied to the substrate at substantially right angles to the substrate at a temperature near the temperature at which the first ion exchange step was conducted, provided that the side of the substrate which had the ion exchange-control film is used as a positive potential side; and a second ion exchange step in which the resulting glass substrate is subjected to thermal ion exchange by immersing the substrate in a second molten salt containing a second monovalent ion capable of changing the refractive index of the substrate in a manner contrary to the first monovalent ion.
