Abstract: Embodiments provide an LED comprising a quantum well region operable to generate light and a substrate having an interface with the quantum well region, wherein light generated by the quantum well region traverses the interface to enter the substrate and exit the LED through an exit face of the substrate. The exit face may be opposite from and a distance from the interface, with some portion or all of this LED being shaped to optimize the light extraction efficiency of the device. The exit face can have at least 70% of a minimum area necessary to conserve brightness for a desired half-angle of light. Sidewalls of the LED may be positioned and shaped so that rays incident on a sidewall reflect to the exit face with an angle of incidence at the exit face at less than or equal to a critical angle at the exit face.

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.

Abstract: A digital film processing system operating to correct electromagnetic radiation from an image to an electronic representation of the image, whereby a waveguide device is utilized to direct light from a light source to the film in order to illuminate images more uniformly.

Abstract: One aspect of the invention is a system for digital film processing. A point light source, such as a laser, directs light onto film coated with a processing solution. Light from the film is measured to produce sensor data that corresponds to the colors in the film. The sensor data is used to construct a digital image corresponding to an image recorded on the film. Another aspect of the invention is a shaped collector that focuses light from the film to a focal point within the shaped collector.
