Claims13
A mold for manufacturing a lens comprising a first curved surface having a first focal distance and a second curved surface having a second focal distance, the mold comprising:
- an inner surface, comprising a first mold surface and a second mold surface respectively configured to shape the first curved surface and the second curved surface of the lens;
- and
- a side wall, extended out from an edge of the inner surface.
An optical machine structure, comprising:
- a light source, configured to project light toward a working surface to generate reflected light;
- a multifocal lens, comprising:
- a first curved surface, having a first focal distance;
- and
- a second curved surface, having a second focal distance, wherein the first curved surface and the second curved surface are interlacedly arranged along a radial direction of the multifocal lens on a light incident surface;
- and
- an optical sensor, configured to receive the reflected light via the multifocal lens.
