Abstract
A waveguide device including a light transmitting body having a first surface, a second surface, and a longitudinal axis where at least one of the first and second surfaces, and preferably both surfaces, are configured to extent in a direction non-parallel to the longitudinal axis. The body of the waveguide can be configured in an elliptical shape along the longitudinal axis, whereby a proximal portion of the waveguide device is symmetrical with a distal portion. The waveguide device being elliptically configured can be combined with a light to form an optical transfer system.
Claims20
A waveguide device, comprising:
- a light transmitting body having a first surface extending from a light source end to an image plane end, a second surface extending from the light source end to the image plane end, wherein the second surface substantially opposes the first surface, and a longitudinal axis defined between the light source end and the image plane end, wherein at least one of the first and second surfaces is extended in a direction non-parallel to the longitudinal axis.
An optical transfer system, comprising:
- (a) a light source operable to produce electromagnetic energy;
- and
- (b) an elliptically configured waveguide device comprising a light transmitting body having first and second surfaces substantially extending between a first end and a second end, wherein the waveguide device is operable to receive the electromagnetic energy from the light source.
A waveguide device comprising a light transmitting body having a first surface, a second surface, and a longitudinal axis, wherein at least one of the first and second surfaces is configured to be oriented non-parallel to the longitudinal axis and at least one of the first and second surfaces comprises a coating material.
