摘要： A method for producing an aspherical structure according to the invention includes the steps of: forming a layer on a surface of a substrate so that the layer exhibits an etching rate distribution in a direction perpendicular to the surface of the substrate; forming a mask having a predetermined opening shape on the surface of the layer; and etching the layer to thereby form at least one aspherical concave portion. When each concave portion is used as a molding tool so that a resin with which the concave portion is filled is solidified and removed from the concave portions an aspherical lens array can be formed accurately.

摘要： A projection-type image display device includes a transmissive image display panel having a matrix of pixels arranged at different pitches in different directions perpendicular to each other, and a planar microlens array for converging light emitted by a light source onto the transmissive image display panel. The planar microlens array comprises a substrate and a matrix of microlenses disposed on the substrate for converging the light onto the pixels, respectively, each of the microlenses being of an oblong shape. Each of the microlenses may have a longitudinal axis inclined with respect to an axis of the matrix of pixels to cover the pixel aperture of one of the pixels. The oblong shape of each of the microlenses may be composed of a pair of spaced identical semicircles and a rectangle interconnecting the identical semicircles and having sides of the same length as the diameter of the semicircles. Since the oblong microlenses are shaped to fully cover the pixel apertures of the corresponding pixels, the light from the light source is efficiently converged onto the pixels by the microlenses to produce light display images.

摘要： According to the present invention, there is provided a method of designing a collimator array device which enables reduction of the insertion loss because of the variation of the optical length. When the beam waist is positioned at the intermediate position between the emitting side planar microlens and the receiving side planar microlens (d1=L/2), the distance d0 between the emitting side fiber array and the emitting side planar microlens can be used as the distance between the receiving side fiber array and the receiving side planar microlens, and thereby the design of the collimator array device can be simplified. The distance d0 for satisfying d1=L/2 is calculated and two values d0-2 and d0-4 are obtained. By selecting the smaller value d0-2, it is possible to reduce the insertion loss because of the shift at the time of coupling.

摘要： The present invention provides a method for manufacturing an erect image, unity magnification, resin lens array by injection molding. Two injection-molded lens plates are stacked such that convexly warped sides thereof face each other or such that a convexly warped side of the lens plate whose warp is greater than that of the other lens plate faces a concavely warped side of the other lens plate, while directions of resin injection thereof are aligned so as to optically avoid the influence of molding shrinkage. Engagement spigots and engagement sockets are employed in order to align the two lens plates. The two stacked lens plates are secured by clipping of peripheral portions thereof.
