In order to measure the UV beam effctively, we bought a low cost, high QE, back-thinned CCD camera from 
Fingre Lakes Instrumentation.

External Triggering
The IMG's RJ11 connector next to the USB connector has 6 pins. Pin 1 is closest to the USB connector.
Pin 2 is electrical ground and Pin 3 is the logic input. (This input has a 3.3K pullup resistor to +5V).
The camera can be triggered by shorting pin 3 to pin 2.
In FLIGrab:
1. Run FLIGrab
2. Select the Shutter Control
3. On the pull down menu, select 'External trigger on LOW'
4. Press Done
5. Open the Grab Menu
6. Select desired frame and exposure settings
7. Click the Grab button
8. Short pin 3 to pin 2
9. The shutter will trigger
Note that the trigger can be changed to a rising edge input (pin 3 goes from 0V to +5V) by selecting External trigger HIGH in the hutter
control menu.
Also note that if you cannot find the 6 pin RJ cable, you can use a 4 pin cable!! With a 4 pin cable, the wire closest to the USB connector makes contact with pin 2 on the RJ-11 connector.
Therefore, for a 4 pin cable, connect the wire closest to the USB connector to ground and use the second wire as the trigger signal.
