Standoffs and Guide Rods
After closer inspection of other small optics, it is clear that the guide rods should be
the standoffs on our small optics. Yoichi took a picture of the SRM that shows this clearly. This makes sense since the tension of the wire will make the standoff 'want' to go up during pre-epoxy adjustment, so the guide rod prevents the standoff from popping up and out.
Looking at the side of the PRM without the groove, it looks like there is lots of space between the guide rod and the alignment etch in the glass, so we can just place a standoff directly under the guide rod that is present.
A spare standoff is being shipped tomorrow morning, so we should have it by Monday for installation on the PRM.
