Abstract: An image light projection screen has a plurality of aperiodic lens array units on a main surface. The aperiodic lens array units are arrayed two-dimensionally regularly and without any gap at least in an image display region. Each aperiodic lens array unit includes at least four apexes of micro-lenses each having a curved surface shape and arranged without any gap and non-periodically, and has symmetry keeping continuity of the curved surface shapes of the micro-lenses located in a boundary portion.

Abstract: An optical element in which transmittance of light monotonically decreases from a center portion toward a peripheral portion, includes a light absorbing portion, made of a material that absorbs a part of or all of visible light, formed at one surface of a transparent substrate such that its thickness monotonically increases from the center portion toward the peripheral portion; a light transmitting portion, made of a material that transmits visible light, formed on the light absorbing portion; and a transparent resin layer, made of a material that transmits visible light, formed at another surface of the transparent substrate, wherein each of the light absorbing portion, the light transmitting portion and the transparent resin layer is made of a resin material.

Abstract: A method of producing an optical device, which includes a center region where a light absorbing part is substantially absent, a peripheral region, and an intermediate region between the center and peripheral regions, where the thickness of the light absorbing part gradually increases in a direction from the center region to the peripheral region, includes applying a resin material that absorbs light onto a transparent base material. A forming mold including a convex and a concave corresponding to the shape of the light absorbing part is pressed against the applied resin material. The light absorbing part is formed by curing the resin material through exposure to ultraviolet radiation with the forming mold being pressed against the resin material. A surface of the convex that faces the resin material when the forming mold is pressed against the resin material corresponds to the center region of the optical device and is flat.

Abstract: Disclosed are a diffractive optical element and a measurement device that are capable of reliably suppressing occurrence of a zero-order diffracted light beam and generating light spots in a wide range. The diffractive optical element has concave and convex portions and diffracts incident light in two dimensions to generate diffracted light. When a maximum diffraction angle with reference to an optical axis of the incident light is an angle range ?, the angle range ? is 7.5° or greater, and diffraction efficiency in a zero-order diffracted light beam is 5% or less.

Abstract: A three-way indexable throwaway tip for deep-hole drilling can be used as a center cutting blade body for a drill head in either whole cutting type or uncut core break-off type applications. The throwaway tip for deep-hole drilling is of a thick plate body having a three-fold symmetry with three cutting sections that are rotationally spaced apart at a central angle of 120 degrees. When mounted on a drill head, one cutting section of the throwaway tip faces a drilling direction. The forward facing blade edge of that cutting section includes an inner blade edge shorter in blade length and an outer blade edge longer in blade length forming an apex. The outer blade edge is composed of two consecutive blade edge portions of a peak-side outer blade edge portion having a smaller outer blade edge angle and a corner-side outer blade edge portion having a larger outer blade edge angle.
