A collector for propagating incident radiation to a remote location. The
collector comprises, a light directing component coupled to a buffer
component, a first propagation component coupled to the buffer component
and configured to transmit the incident radiation into a collector region
through one of a plurality of windows, and an optical transport assembly
coupled to an end of the collector region and having a second propagation
component. Each light directing component is configured to redirect the
incident radiation from a first direction to a second direction, and the
collector region includes a plurality of regions exhibiting a refractive
index value that gradually transitions from about 1.5 to about 2.0. The
second propagation component is further configured to retain the incident
radiation.
