Abstract
The invention provides an optical part, whose set-up position, shape, and size are properly controlled, and its manufacturing method. The optical part of this invention can include a substrate having an optical surface, a spire part being set up in a manner of surrounding the optical surface, and an optical member at least partly being placed on the optical surface. A tip of the spire part is located at a higher position than the optical surface.
Claims13
An optical part, comprising:
- a substrate having an optical surface;
- a spire part that is disposed so as to surround the optical surface, the spire part having a first surface that faces the optical surface and a second surface that faces away from the optical surface, the first and second surfaces being inclined surfaces with respect to a surface of the substrate;
- an optical member disposed on at least part of the optical surface;
- and
- a tip of the spire part being located at a higher position than the optical surface, the first surface intersecting the second surface at the tip of the spire part.
