| If you don’t see the hyperfine transitions, more than likely the pickoff beams in the spectroscopy module need adjustment. Make sure all four screws are holding down the DBR and spectroscopy modules. Loosen the spectroscopy module screws and try making small adjustments while looking at the ERROR IN signal. You can also try scanning the laser current. | If you don’t see the hyperfine transitions, more than likely the pickoff beams in the spectroscopy module need adjustment.

| If you have a D2-110 and you still cannot see spectroscopy, remove the screws to the top of the spectroscopy module and adjust the course steering mirror (see below). | If you have a D2-110 and you still cannot see spectroscopy, remove the screws to the top of the spectroscopy module and adjust the course steering mirror. Likewise, with the D2-210, you can adjust input PBS. (See below.) |
