A product includes a fine periodic structure having a plurality of projection portions extending parallel to each other in a first direction in each of a first region and a second region adjacent in the first direction on a surface of a substrate. The fine periodic structure formed in an inner portion of the first region and the fine periodic structure formed in an inner portion of the second region are substantially the same periodic structures. End portions of the plurality of projection portions formed in the first region and end portions of the plurality of projection portions formed in the second region are formed in a boundary portion between the first region and the second region.

Surface treatment method, manufacturing method for product, surface treatment apparatus, and product

A product includes a first concave portion and a second concave portion on a curved surface and a third concave portion on an opposite side of the second concave portion from the first concave portion. A first direction from a bottommost point of the first concave portion to a midpoint between the first and second opening ends of the first concave portion is different from a third direction from a bottommost point of the third concave portion to a midpoint between the first and second opening ends of the third concave portion. A second direction from a bottommost point of the second concave portion to a midpoint between the first and second opening ends of the second concave portion is a direction between the first and third directions. A reference line passing through the first and second opening ends of the third concave portion is orthogonal to the third direction.

Molded product

An imaging apparatus includes a first reflection optical system and a second reflection optical system having mutually different optical axes, each of the first and second reflection optical systems includes a plurality of reflecting surfaces, a first imaging portion configured to receive an imaging light reflected by the first reflection optical system, a second imaging portion configured to receive an imaging light reflected by the second reflection optical system, a first member, a second member, and a frame. A part of the plurality of reflecting surfaces of the first reflection optical system are reflecting surfaces provided on the frame. Among the plurality of reflecting surfaces of the first reflection optical system, a final-stage reflecting surface configured to reflect the imaging light toward the first imaging portion is a first reflecting surface formed on a surface of the first member.
