Spectroscopy-Mount Adapter
The PI-MAX is supplied with a spectroscopy-mount adapter if one was specified when the
system was ordered. The spectroscopy-mount adapter is simply screwed directly into the
nose and then secured by three set screws. If you want to change from one adapter type to
another (e.g., C-mount to spectroscopy-mount), loosen the three setscrews, unscrew the
current adapter, screw in the new adapter until it bottoms out, and secure the adapter with
the locking setscrews. The focal length distance will automatically be correct to a high
degree of precision. However, there will be the usual focal depth adjustment and
rotational adjustment at the spectrograph input or output.
