摘要： In a method for forming a planar microlens according to the present invention, a wet etching is conducted to a glass substrate for a stamper while it is covered with a mask. After the etching is conducted and the mask is removed a wet etching is conducted again to the glass substrate to form densely arranged concave portions thereon, and thereby a stamper is obtained. An uncured resin is applied on the forming surface of the stamper, a glass substrate for a planar microlens array (MLA) is pressed thereto, and thereby the uncured resin is formed. The uncured resin is cured by applying an ultraviolet irradiation thereto and the stamper is released therefrom. The resin layer is removed by a reactive ion etching and whereupon the substrate is etched in a form corresponding to the form of the resin layer and whereby an all-glass microlens of high precision is obtained.

摘要： A glass substrate is irradiated with a converged laser beam to thereby form a spherical or nearly spherical convex portion on a surface of the glass substrate. More preferably, there may be used a method including the steps of: sticking a glass substrate to a flat member having a predetermined spherical or aspherical concave portion formed therein; and irradiating a converged laser beam onto a surface of the glass substrate just under the concave portion while making the converged laser beam penetrate through the flat member to thereby form a spherical or aspherical convex portion in the inside of the concave portion in accordance with the shape of the concave portion.

摘要： A projection-type image display device includes a transmissive image display panel (1) having a matrix of pixels arranged at different pitches in different directions perpendicular to each other, and a planar microlens array (4) for converging light emitted by a light source (16) onto the transmissive image display panel. The planar microlens array comprises a substrate (3) and a matrix of microlenses (2) 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 light source is efficiently converged onto the pixels by the microlenses to produce light display images.

The optical input/output port has a glass substrate attached to the electronic circuit board, a first array of optical sensors for absorbing a portion of a light beam applied thereto from the light source and photoelectrically converting the portion of the light beam, and for transmitting the remainder of the light beam therethrough, and a second array of spatial light modulators for modulating the transmittance with respect to a light beam applied thereto, the first and second arrays being disposed on a surface of the glass substrate in superposed relationship to each other. A motherboard comprises a substrate and a coaxial lens array of lenses spaced at equal intervals along an optical axis on the substrate, with conjugate focusing planes of equal magnification being disposed between adjacent ones of the lenses. A method of manufacturing the motherboard is also disclosed.

摘要： A planar microlens array includes an array of convex microlenses made of an ultraviolet-curable synthetic resin having a high refractive index and disposed on a surface of a base glass plate. A cover glass plate is bonded to the array of convex microlenses by an adhesive layer made of an ultraviolet-curable synthetic resin having a low refractive index. A film made of an ultraviolet-curable synthetic resin is applied to a surface of the base glass plate remote from the array of convex microlenses. The film serves to prevent the planar microlens array from being warped when the ultraviolet-curable synthetic resin of the array of convex microlenses and the adhesive layer are cured.
