COMMENT ON SAM 25 - Replace SLM0R02 Imager
Attempted to align the SL into the camera without success. Found a vertical strip at turning mirror motor position X=6.98mm & y=7.90mm. These values are close to lab alignment numbers. Will need to have about have a day access to check the alignment downstream of the turning mirror.
