    Just a quickie to show the most recent incarnation.

    A commercial 55mm lens in place of the ‘standard’ 30mm diameter doublet.  (Upper and lower covers removed for clarity).

    Much better end-to-end focusing across the visible range.  This looks to be a marked improvement.

    Look how much space it frees up inside the body of the spectrograph and underneath the body for additional automation fixtures.  The new SAS developed calibration ‘injector’ & lamp controls, focusers, grating motor, etc can now be added.
