A resin molding has a first surface and a second surface, wherein the second surface includes a rib, and wherein the first surface includes a glossy portion and a non-glossy portion.

Resin molding, printer, and method for manufacturing resin molding

An optical element formed of a plurality of materials includes a middle layer between a base material and a reflecting member so as to suppress stripping, cracking and the like of the optical surface due to the difference in coefficients of thermal expansion among the component materials, in the case where a temperature difference in the service environment or a temperature difference between a manufacturing environment and the service environment is large.

Optical element, spectroscopic apparatus, and method for manufacturing the same

A resin product including an antireflection surface includes a plurality of first concave portions, a plurality of second concave portions, and a component surface. The first concave portions have opening widths equal to or larger than 1 &#x3bc;m and equal to or smaller than 300 &#x3bc;m. The second concave portions are formed on each of the plurality of first concave portions and have opening widths equal to or larger than 10 nm and equal to or smaller than 1 &#x3bc;m. The component surface is configured to surround each of the plurality of first concave portions.

Resin product, method of making resin product, interchangeable lens, and optical device

A diffusing plate includes a microlens array in which a plurality of microlenses are arranged, wherein the microlenses have such a shape that a curvature of a sectional shape including a center line of the microlenses varies depending on a direction of the center line, and wherein microlenses that are different in the direction of a center line where the curvature of the outline is largest are arranged.
