►Folding mirrors
We use 2inch mirrors (d2" x t3/8") mirrors for the PRC/SRC folding mirrors.
Their name has been changed such that the definition agrees with the AdvLIGO naming. (12/01/2009)

R for 532nm to be considered!
At the installation in 2010, G&H HR mirrors were used for the TT mirrors. This results very little transmission through those mirrorrs (<25ppm).
