Zoom
in on the central peak.
9.
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 5 pixels wide across the Full Width of
Half the Maximum height (FWHM). Excessive asymmetry of the peak is a sign
that the slit image is not aligned to the pixel columns; diminished shape and
magnitude are symptomatic of defocusing.

Stop
the acquisition.

Select
Continuous
and
Run
the experiment. When aligned the five spectra will
overlap but may not show similar intensity. Each spectrum should be 3-5 pixels
wide at FWHM. To adjust the focus of the CCD camera, rotate the focus wheel
with your fingers to drive the CCD flange out from the body. To bring the camera
focus in, it is necessary to hold the camera against the wheel while rotating the
focus wheel.
14.
To adjust the alignment (rotation) of the CCD camera, insert a 1.5 mm allen key
into the hole in the side of the unit to engage the CCD rotation adjustment set
