ABSTRACT:
A light delivery technique includes optical configurations as well as the associated methods that generate a ring beam from a linear light source. In one embodiment, a remote light source module delivers illumination light to a fundus camera and/or slit lamp. In another embodiment, an arrangement combines the use of a light pipe homogenizer and a ring beam transformer for efficiently collecting light from a substantially axially linear light source, homogenizing the collected light that lacks low angle flux relative to the optical axis, and transforming the light into a ring beam with a substantially improved low angle flux distribution. In still another embodiment, light emitted from a substantially axially linear light source is directly collected by a curved surface mirror and spatially filtered into a ring beam. The ring illumination beam can be co-axially projected on a sample such as the pupil of a human eye and at the same time the light beam also has a large enough relatively uniform angular flux distribution so that a wide area on the retina of the eye can be uniformly illuminated.
