This is a list of the ISC diagnostic optics in HAM1. Some of these are yet to be installed, but all will be installed in this installation window.
The only differences between this and D1000313 are:

HW1 | 1" IR half wave plate from ALS stock | N/A (no marking) | rotator mount | for REFL | newly put in |
Note:
We rejected one optic (E040512-B3, IO822-07 on the barrel) because there were many (not too many) defects or particulates that we couldn't remove by nitrogen gun, gentle push using a wipe, nor a serious cleaning effort using methanol and a wipe.
It is still OK-ish, but it's not spotless either. I would have used that if nothing else is available. Anyway, that optic is now in "clean, with issues, or from SQZ" optics bin in the optics lab.
