Aluminum Circular Variable Beamsplitters are designed to split an incident beam into a transmitted and a reflected beam. The beamsplitter coating material is protected aluminum, which has substantially less absorption loss than the conventional inconel coating. Both surfaces are coated with a broadband anti-reflection coating to reduce secondary images. The filters are designed to be used at 45 degrees.
