Abstract
A focusing device includes a substrate and a plurality of scatterers provided at both sides of the substrate. The scatterers on the both sides of the focusing device may correct geometric aberration, and thus, a field of view (FOV) of the focusing device may be widened.
Claims20
A focusing device comprising:
- a substrate;
- a first thin lens provided at a first surface of the substrate and comprising a plurality of first scatterers;
- and
- a second thin lens provided at a second surface of the substrate and comprising a plurality of second scatterers,
- wherein the plurality of first scatterers of the first thin lens are configured to correct geometric aberration of the second thin lens.
2 more elements
A beam scanner comprising:
- an optical path modifier comprising a substrate, a first thin lens provided at a first surface of the substrate and comprising a plurality of first scatterers, and a second thin lens provided at a second surface of the substrate and comprising a plurality of second scatterers;
- and
- a light source array spaced apart from the second surface of the substrate and comprising a plurality of light sources,
- wherein the plurality of first scatterers of the first thin lens are configured to correct coma aberration of the second thin lens.
1 more element
A scope device comprising:
- an object lens unit comprising a substrate;
- a first thin lens provided at a first surface of the substrate and comprising a plurality of first scatterers, and a second thin lens provided at a second surface of the substrate and comprising a plurality of second scatterers;
- and
- a light source facing the second surface of the substrate and configured to emit light on a target object,
- wherein the plurality of first scatterers of the first thin lens are configured to correct coma aberration of the second thin lens.
