Knob for locking GPM3 in
position
For precise levelling the GPM3 is
fitted onto the NA2 telescope
objective and locked in position
with the knob (4).
By turning the micrometer knob
the parallel-sided glass plate is
tilted, thereby causing the line of
sight to be raised or lowered. The
range of displacement is 10mm.
On the scale, seen in the GPM3's
eyepiece, the amount of
displacement is read directly to
0.1mm and estimated to 0.01mm.
