Today Jason and I continued with the CO2 beam scan work in 74760. We did a rough alignment along the profiler, swapping the final mirror from 1" to 2" for easier alignment  and checked that the profiler could see the beam. With the 7.5" FL lens on the front, the beam is too large for the profile after ~300mm. It's also quite large before the lens.

Parts stored in the same locations as last week, optics and Nanoscan still in CO2X enclosure. First optic was moved out of the beam path but we drew around the base with red pen. We should think carefully about if this data will be useful before continuing as will need ot find a different lens to successfully scan.
