System Setup
Introduction
This chapter includes general instructions for setting up a PI-MAX system for operation
in both imaging and spectroscopic applications. For microscopy applications, also see
Chapter 12, Microscopy Applications.
Dangers and Warnings
Voltages inside the PI-MAX may exceed 6,000 volts. To avoid possible hazard to
personnel, use the instrument only according to the directions in this manual and only for
the purposes for which it is designed. Never attempt to operate the PI-MAX with its
covers removed.
Image intensified detectors can be destroyed if exposed to excessive light levels.
Princeton Instruments cannot take responsibility for PI-MAX detector damage due to
misuse. Intensified cameras are particularly susceptible to overload damage when
operated in conjunction with high-intensity light sources such as lasers. Spot damage can
occur without the overload condition being detected.
The PI-MAX has an audible alarm and shutdown circuit to bias the photocathode OFF if
excessive photocathode current is detected. The circuit automatically resets and biases the
photocathode back on after about 0.5 seconds. The short-term protection provided will
not prevent intensifier damage if excessive light is allowed to continuously fall on the
intensifier. It is also possible for excessively bright spots to damage the intensifier tube
without triggering the alarm.
Unpacking the System
During unpacking, check the system components for possible signs of shipping damage.
If there are any, notify Princeton Instruments and file a claim with the carrier. Be sure to
save the shipping carton for inspection by the carrier. If damage is not apparent but
system specifications cannot be achieved, internal damage may have occurred in
shipment. Please save the original packing materials so you can safely ship the camera
system to another location or return it to Princeton Instruments for repairs if necessary.
Checking the Equipment and Parts Inventory
Confirm that you have all of the equipment and parts required to set up the PI-MAX
system. A typical system consists of:
PI-MAX camera (Gen II or Gen III).
ST-133 Controller.
