Initial Power-up and Operation
24
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.
7.
Stop the acquisition.
8.
Using the software, divide the chip to five equal areas.
9.
Run the experiment continuously at the initial reference wavelength.
10.
When aligned, the 5 spectra will overlap but may not show similar intensity. Each
spectrum should be 3-5 pixels wide at FWHM.
11.
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.
12.
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
screw. Turning the screw into the body (clockwise) will push against the pin on
the CCD flange rotating the camera. To rotate in the opposite direction, you need
to turn the camera against the rotation adjustment screw while turning the screw
counter-clockwise.
13.
When the focus and alignment of the camera are properly set, tighten the flange
lock to clamp the CCD flange in position.
14.
To lock the focus wheel in its current position, turn off the light source, remove
the top cover of the spectrograph and tighten the focus lock set screw. If it is
necessary to remove the CCD for some reason, simply loosen the flange lock set
screw and remove the CCD. This Quick-Align CCD adapter mechanism allows
easy replacement of the CCD with minimal realignment.
