270M
Rapid Scanning Imaging Spectrograph
If your 270M has motorized swing-away side entrance or exit mirrors (220AMRN
or
270AMRX), the restraints must be removed. Taking care to avoid touching the any
mirror surfaces, using wire cutters, cut the nylon straps that hold the mirrors against
the side walls. See Figure 3
to
locate the restraints.
WARNING: Never move the swingaway mirrors by hand when the power is on. The
miniature gearhead motors are delicate and expensive. Forcing them manually may
result in time consuming, costly repair.
If you have a grating turret, remove the foam block that is packed above
it,
along with
the tape that secures the block.
Save
the block , for if you ever need
to
ship your
270M for any reason, the block is needed to repack the instrument.
Last, while holding the plastic grating cover
in
place, CAREFULLY remove the tape
that holds the cover on the grating
(If
you have a turret, only the grating facing the
interior of the 270M is covered, be careful to avoid touching the surface
of
the other
grating). When the tape is removed, hold the bottom edge of the cover
in
place, and
tilt the top edge
of
the cover away from the grating, then move the cover down and
away from the grating. This technique minimizes the risk of grating damage. Anything,
including dust, smoke,
or
organic vapors, that comes in contact with the surface of the
grating is likely to cause damage or loss of reflectivity.
2.2.2 Environmental Considerations:
Your spectrometer should be kept
in
an atmosphere free of dust, corrosives and
smoke. For specified performance, the 270M should be operated in a room where
temperature control is maintained within ±
20
C.
