Abstract
A lens assembly having a housing, an interior cavity, a first lens, and a second lens. The housing includes a reflective surface substantially covering at least a portion of an inner surface of the housing. The interior cavity is substantially surrounded by the inner surface of the tubular housing. The first lens extends across the first end of the housing, and it is configured to receive light from a scene outside of the lens assembly and refract the light into the interior cavity of the lens assembly. The second lens extends across the second end of the tubular housing, and it is configured to receive light from the interior cavity of the lens assembly and refract the light to a region outside of the lens assembly. Related methods are also disclosed.
Claims24
A lens assembly comprising:
- an elongated, tubular housing including a first end and a second end opposite the first end;
- an interior cavity within the elongated, tubular housing;
- a reflective surface covering at least a portion of an inner surface of the interior cavity and configured to reflect light received from the interior cavity back into the interior cavity;
- a first lens extending across a portion of the first end of the tubular housing, the first lens configured to receive light from a scene outside of the lens assembly and to refract the outside light into the interior cavity of the lens assembly;
- and
- a second lens extending across a portion of the second end of the tubular housing, the second lens configured to receive light from the interior cavity of the lens assembly and to refract the inside light to a region outside of the lens assembly.
An accessory lens for a camera on a mobile device comprising:
- a housing including a first end and a second end opposite the first end;
- an interior cavity substantially surrounded by the housing;
- a first lens at the first end of the housing, the first lens configured to receive light from a scene outside of the accessory lens and refract the outside light into the interior cavity of the accessory lens, the first lens having a back focal length;
- and
- a second lens at the second end of the housing, the second lens configured to receive light from the interior cavity of the accessory lens and refract the interior light to a region outside of the accessory lens, the second lens having a front focal length, the second lens being separated from the first lens by a distance substantially equal to a sum of the back focal length of the first lens plus the front focal length of the second lens.
A lens assembly comprising:
- an elongated, tubular housing including a first end and a second end opposite the first end;
- an interior cavity within the elongated, tubular housing;
- a first lens extending across a portion of the first end of the tubular housing, the first lens configured to receive light from a scene outside of the lens assembly and to refract the outside light into the interior cavity of the lens assembly;
- and
- a second lens extending across a portion of the second end of the tubular housing, the second lens configured to receive light from the interior cavity of the lens assembly and to refract the inside light to a region outside of the lens assembly;
- in which the first lens and the second lens are configured to produce a selective focus in an image based on one or more of field curvature, astigmatism, and spherical aberration of the first lens or the second lens.
