Abstract:
Results of the optical contamination cavity tests for the Optek IR-LED OP232 and the Centronics BPX65, which are used in the B-OSEM assembly in Advanced LIGO, are given in this document. Both devices (40 each, non-operating but vented) were tested together in the cavity due to schedule needs. The potential optical absorption and scatter loss due to the presence of this device is within acceptable limits. Use of these devices in the B-OSEM assembly is approved.

Emitter: Optek OP232 - info & data-sheet etc. can be found on the following link: http://www.optekinc.com/products/opto_component_TO_46.asp
(n.b. variants of the OP232 are available, usually denoted by adding an additional character to the part code e.g. OP232W for "wide" angle lens version. We are using the standard lens option)
