2.7 System Operation
It is important that the VM-502 be connected to the computer and be initialized before the
controlling software is started.
If the VM-502 is part of a system that includes a Princeton Instruments SpectraHub
Detector Interface and a single point detector such as a PMT or a Silicon Diode detector,
then the entire system will be controlled through the Princeton Instruments SpectraSense
software. The software automatically detects the VM-502 and sets up all necessary
parameters for its operation.
If the VM-502 is part of a system that includes a Princeton Instruments CCD camera,
the system is then controlled either through SpectraSense software mentioned above
or through Princeton Instruments WinSpec software. If using WinSpec, you must set
up the Spectrograph parameters by selecting AM505 in "Define Spectrograph" and by
setting the focal length to 200 mm, the included angle to 64 degrees and the detector
angle to 32.5 degrees in calibration. Follow the instructions in the WinSpec manual for
CCD calibration.
Now that you have completed the hardware and software installations, refer to
Section III.
