DCN Updated R3 Coating Specification

Document #:

LIGO-E0900331-v1

Document type:

E - Engineering documents

Abstract:

This DCN reflects the elimination of the R3 figure change before/after coating specification.

Tolerance on the R3 optic sag is roughly 200 nm over the 54mm beam radius. The 8 nm requirement was placed on the R3s by similarity. It is too restrictive.
