We have received a ROM cost from IC Optical Systems, based on a verbal coating spec.
Points to mention in reply to ICOS:
- Do the fabrication tolerances meet our spec ?
- lambda/10 flatness but we asked for lambda/20
- Beamsplitter coating performance not good enough
- Is button approach still feasible?
- What overcoat is assumed for the silver full reflector mirrors?
JC will send a preliminary coating spec to SESO, in order to elicit a comparable ROM estimate.
