【 摘 要 】

We received funding to fabricate and characterize dichroic beamsplitters for optical filtering applications in astronomical instrumentation. A competitive bidding process led to the selection of a vendor who has successfully fabricated subcomponents that meet our optical specifications. The final assembly of the subcomponents into a complete optical module is under way, and we expect final delivery of the part to our laboratory in May 2009.
