Mike Smith provides an analysis of the angular acceptance required of the Beamsplitter coating based on the as built wedges for CP and BS. These wedges came in considerably tighter than our specification, allowing us to provide a narrower acceptance angle for the Beamsplitter coating. This gives our coater a better chance of hitting 50% precisely.
