ANTIREFLECTION STRUCTURE, OPTICAL UNIT, AND OPTICAL DEVICE
First Claim
1. An antireflection structure for reducing reflection of light having a wavelength equal to or larger than a predetermined wavelength, and absorbing the light whose reflection the reflection is reduced, the structure comprising:
- a base structure portion which is configured to have a plurality of structural units arranged on a reference plane, and each having tilted surfaces so that an angle between each of the tilted surfaces and a reference plane is a predetermined angle, anda plurality of fine concave/convex portions formed on a surface of the base structure portion, and arranged within a cycle equal to or smaller than the predetermined wavelength.

Abstract
An antireflection structure having a high antireflection effect is provided.
An antireflection structure (50) reduces reflection of light having a wavelength equal to or larger than a predetermined wavelength, and absorbs the light whose reflection is reduced. The antireflection structure (50) includes a base structure portion (7) which is configured to have a plurality of structural units (70) arranged on a reference plane, and each having a tilted surface (71) so that an angle between the first side surface (71) and a reference plane (51) is a predetermined angle, and a plurality of fine concave/convex portions (8, 8, . . . ) which are formed on a surface of the base structure portion (7), and arranged within a cycle equal to or smaller than the predetermined wavelength.
