270M
Rapid
Scanning Imaging Spectrograph
5 Accessory Installation:
A full line
of
accessories are available for the 270M from light sources, optical fibers
and interfaces
to
detectors and sample compartments. Most
of
these are shipped with
separate documentation. The accessories described here are only those which are
user installable and, in effect, become part
of
the 270M.
5.1
270MCA Spectrograph
Exit
Port Installation:
If your 270M has a spectrograph exit port for an array detector, remove
all
of
the tape
and the cover plate from the adapter flange and find the two 10-32 oval point retaining
screws that will hold the detector mounting cup inside the adapter flange. If your 270M
was shipped together with an array detector purchased from Spex on the same order,
the detector mounting cup may be mounted
to
your detector. Otherwise, mount the
cup to your detector with the three 8-32 flat head screws, washers, and nuts provided.
If you have a 226MCD shutter that was not factory installed, install it on the front
surface
of
the detector mounting cup.
See
the Accessories section for instructions.
Insert the detector mounting cup, with the detector attached, into the adapter flange. If
your array detector was shipped from Spex with the mounting cup attached, there .
may be pencil marks at the top of the cup and the adapter flange
to
provide a
reference location for detector alignment. Snug the two 10-32 retaining screws
to
hold
the detector. See the alignment section for final adjustment.
5.2 225MCD Shutter:
This external mount shutter replaces the spacer/ height limiter at the entrance slit. It is
intended for exposure control on a Spectrum One CCD and QuikScan
PDA
detector
systems. To install it, remove the four 6-32 socket head capscrews along with the
spacer and remove the two 10-32 setscrews
to
the right of the slit. Then open the
cover and attach the 225MCD in its place with the two 6-32 and two 10-32 screws
provided with the shutter. replace the cover
to
the shutter. ·
The BNC connector
on
the right
·side
of
the shutter housing connects
to
the shutter
cable
of
a Spectrum One
or
QuikView detection system.
