Patent ID: 8094388

Claim:
A modular optical package comprising; a. an enclosure having at least one ingress portal at least one egress portal, an enclosure case and an enclosure base; b. a beam circularization element within said enclosure; c. at least one retention mechanism in said enclosure base; wherein said enclosure case and enclosure base form an enclosure space specific to said beam circularization element contained therein; wherein said ingress and egress portals are capable of transmitting electromagnetic radiation through said enclosure space; and wherein said retention mechanism allows said enclosure base to be affixed to a separate mounting block comprising an electromagnetic radiation source so as to maintain said modular optical package in a fixed position relative to said electromagnetic radiation source such that when said mounting block and said retention mechanism are engaged, said ingress portal, egress portal and circularization element form an optical modification pathway relative to said electromagnetic radiation source in said mounting block.
