I'm getting ready change the Newport Ultima U100-AC to SS-Polaris-K1 LOW DRIFT MIRROR MOUNTS
Note: there is only one lens in the PRM lunching path ( only realized later ) , so the spots are large ~ 3 mm at PRM qpd and ~4.5 mm at BS qpd
The spots are well centered.
Atm3, the spots were well centered yesterday ( the PRM is misaligned in pitch and retsore does not work today )
