Information of Core Optics
Basic information
Substrate Material: The material of the substrate is Corning 7980 Fused Silica, grade UV-0A. [http://www.corning.com/docs/specialtymaterials/pisheets/H0607_hpfs_Standard_ProductSheet.pdf Link to the data sheet of Corning 7980]
Calculation of the RoC spec Considerations on the parameters of PRC/SRC
- PRMs and SRMs will have the wedge angle larger than the spec (see below). PRMs were returned for repolish. Thus, their wedge angles might be vary. This is to be confirmed.

Notes on Installed Suspensions
- PRM was pulled from the vacuum in August 08 after an earthquake. A wire standoff was found to have come off, and was sitting on the optical table. The standoff was replaced. There is no guide rod on the left/south side.
