Maintenance
IMPORTANT: Always handle the spectrometer
and its accessories with care to avoid scratching
the optical surfaces and throwing off the align-
ment. Also, when not in use, the spectrometer
should be stored in its hardwood case.
Periodically clean the telescope aperture, the collimator
aperture, and the prism with a nonabrasive lens paper
(available at any camera store). No other regular mainte-
nance is required.
