The ETMU05 has been removed from the suspension and put into the little foil house.
Before removing it I checked the position and pitch of the optic with reference to the table top.
Using the traveling microscope I checked the height of the scribe lines from the table top. They are at equal heights, centered on 5.5 inches, correct to about a quarter of the width of the scribe line.
The retro-reflection of the He-Ne laser beam is correct to within one diameter of the beam at a distance of about 1.5m. This is the reflection from the rear, AR coated, surface. The reflection from the front, HR coated, surface was down by about two diameters.
Jenne has checked with Bob and agreed on a date for baking the optic.
