Abstract
An optical device includes: a base that transmits incident light; and a first conductive film formed on one surface of the base, and that includes an indentation pattern of a predetermined period formed on a base-side surface, wherein a side portion defining an edge portion irradiated with the incident light has a form of a protrusion or a straight line as viewed from the incident side of the incident light.
Claims12
An optical device comprising:
- a base that transmits incident light;
- and
- a first conductive film comprising a plurality of side portions formed on one surface of the base and that includes an indentation pattern of a predetermined period,
- wherein,
- a side portion defining an edge portion of the first conductive film that is irradiated with the incident light has a form of one of a protrusion and a straight line as viewed from a side from which the light is incident, and
- the indentation pattern is concentric with respect to an end portion of the edge portion of the first conductive film.
