Introduction
Description
The PI-MTE camera is ideally suited for
operation inside a vacuum chamber. State-
of-the-art CCD arrays are available for the
PI-MTE camera that enable outstanding
performance in a wide range of X-ray
Imaging and Spectroscopy applications.
The PI-MTE camera is also suitable for
medium-low light applications that require
small size or steel case ruggedness.
Figure 1. PI-MTE Camera
Design
PI-MTE cameras have three distinct sections. The front enclosure contains the CCD
array seated on a cold finger. This finger is in turn seated on a two-stage Peltier
thermoelectric cooler. The middle enclosure contains the heat exchanger. The rear
enclosure contains the preamplifier and array driver boards. This keeps all signal leads to
the preamplifier as short as possible, and also provides RF shielding.
Grounding and Safety
The ST-133 Controller that controls the PI-MTE camera is of Class I category as defined
in IEC Publication 348 (Safety Requirements for Electronic Measuring Apparatus). It is
designed for indoor operation only. Before turning on the controller, the ground prong of
the power cord plug must be properly connected to the ground connector of the wall
outlet. The wall outlet must have a third prong, or must be properly connected to an
adapter that complies with these safety requirements.
If the equipment is damaged, the protective grounding could be disconnected. Do not use
damaged equipment until its safety has been verified by authorized personnel.
Disconnecting the protective earth terminal, inside or outside the apparatus, or any
tampering with its operation is also prohibited.
If the PI-MTE camera system is used in a manner not specified by Princeton Instruments,
the protection provided by the equipment may be impaired.
