Abstract
An optical lens includes a plurality of substrates arrayed two-dimensionally or one-dimensionally. A surface of each of the plurality of substrates is provided with a plurality of microstructural bodies corresponding to part of a single lens.
Claims15
An optical lens functioning as a single lens against incident light, the optical lens comprising a plurality of substrates,
- wherein
- each of the plurality of substrates has, on a surface on which the incident light is incident, a principal area that serves as a portion of the single lens and in which a plurality of microstructural bodies is provided at predetermined spacings that are smaller than a wavelength of the incident light,
- the plurality of substrates include a plurality of first substrates each having, on the surface, a peripheral area in which the plurality of microstructural bodies are not provided and that serves as an outer side of the single lens, and
- the plurality of substrates are arranged two-dimensionally or one-dimensionally in a direction parallel to the surface so that the principal areas of the plurality of substrates are joined to each other to form the single lens and the peripheral areas of the plurality of first substrates form an outer shape of the single lens.

A method for fabricating an optical lens including a plurality of substrates and functioning as a single lens against incident light,
- each of the plurality of substrates having, on a surface on which the incident light is incident, a principal area that serves as a portion of the single lens and in which a plurality of microstructural bodies is provided at predetermined spacings that are smaller than a wavelength of the incident light,
- the plurality of substrates including a plurality of first substrates each having, on the surface, a peripheral area in which the plurality of microstructural bodies are not provided and that serves as an outer side of the single lens,
- the method comprising:
- preparing the plurality of substrates;
- and
- arraying the plurality of substrates two-dimensionally or one-dimensionally in a direction parallel to the surface,
- wherein the arraying causes the principal areas of the plurality of substrates to be joined to each other to form the single lens and causes the peripheral areas of the plurality of first substrates to form an outer shape of the single lens.
