Systems and methods for cooling an optic

摘要

Devices are described herein which may comprise an optic having a non-planar surface, the non-planar surface having an optically active portion; and a flow guide directing gas upon the non-planar surface to produce turbulent flow on at least a portion of the optically active portion of the non-planar surface to cool the optic.

1. A device comprising:
an optic having a non-planar surface and an annular periphery, the nonplanar surface having an optically active portion, the optic representing a lens for focusing light passing through the nonplanar surface toward a focal spot; and a flow guide disposed concentrically surrounding and outside of said periphery, said flow guide having a plurality of nozzles disposed on an inward facing surface of said flow guide, said plurality of nozzles directing gas upon said non-planar surface to produce turbulent flow on at least a portion of the optically active portion of said non-planar surface to cool said optic.
