Initial Power-up and Operation
23
2.
Using a 2.5 mm allen key, loosen the M3 cap head screw on the flange lock by
turning the allen key counter-clockwise. This screw is accessed through the flange
lock hole in the side of the unit. Note that when the flange lock is loose, the CCD
flange is free to slide in and out of the unit.
3.
Using a 2 mm allen key, remove the M3 button head screws which secure the top
cover of the unit and remove the top cover.
4.
Using a 1.5 mm allen key, loosen the focus lock set screw (M3).
5.
Replace the top
cover.
6.
The CCD focus
wheel and rotation
adjustment screw are
free to move. The
CCD focus wheel,
touching the inside
face of the CCD
flange, acts as a
focus stop for the
CCD flange. The
CCD rotation
adjustment screw,
touching the pin on
the CCD flange, acts
as a rotation stop for
the CCD flange.

CCD Rotation and Adjustment Mechanisms
Synapse Focus and Alignment
1.
Turn on the light source. Using the software, make the slit width as narrow as
possible (~ 10 µm ) on the detector. This will allow determination of the best
focus.
2.
Manually set the height limiter to 1 mm.
3.
From the software, enter a reference wavelength (such as a Hg line at 546 nm).
4.
Set the detector to Spectral Acquisition mode. Set the data to display as signal
intensity (Y-axis) vs. pixel position (X-axis).
5.
Set the Integration Time to 0.1 second or less, and run continuous spectral
acquisition. While continuously running, adjust the Integration Time until the
observed signal is approximately 40,000 counts.
6.
View the spectra. A focused, aligned CCD will provide a distinct peak of large
amplitude, generally symmetrical to the limits of the design of the spectrometer.
The peak should be less than or equal to 3-5 pixels wide across the Full Width of
Half the Maximum height (FWHM).
