Abstract
A tractrix-based optical device is provided. The tractrix-based optical device includes a light receiving surface, a light emitting surface, and an intermediate portion of transparent material between the light receiving surface and the light emitting surface. The intermediate portion includes a boundary connective surface that adheres to a tractrix when in cross-section to provide total internal reflection of light propagating from the light receiving surface to the light emitting surface. The tractrix-based optical device can align and correlate light from multiple off-axis light emitting elements, or from an extended source light emitting element, thereby providing a generally uniform output distribution.
