In fact, I would need a very very bright light source in order to see the footprint of the beam on the dichroic and IN-TT, to ensure it is fairly centered on the optics. I do not know how bright is ARGOS source as I never used it..if it is not very bright we might ask Tom Herbst if we can use Baby Argos for this phase? Of course for this activity, to preserve detectors we can close SHARK-NIR shutter). Use TECCAM first, and then SCICAM (with ND filter) later for the alignment. |
