Health and Safety Advice
High voltage devices can be hazardous if they are not installed, operated and
maintained correctly, or if a device is damaged. Photek cannot accept responsibility
for damage or injury resulting from the use of Photek devices. Equipment
manufacturers and users should ensure appropriate precautions are taken. Warning
labels and notices must be provided on equipment and in operating manuals.
High Voltage
Equipment must be designed so that operators cannot come into contact with high
voltage circuits. Tube enclosures should have fail-safe interlocked switches to
disconnect the primary power supply and discharge all high voltage capacitors before
allowing access.
X-Ray Radiation
All high voltage devices produce X-rays during operation and may require shielding.
Storage and Handling
Avoid storage or operation of image intensifiers at temperatures greater than +40C.
Room temperature is preferred (21C). Protect the cathode from intense focused
light, sunlight and lasers, even when not running the image intensifier, as this can
lead to local thermal overloads and cathode damage.
Avoid excessive shock or vibration to the image intensifier as this could damage
delicate internal components, such as the MCP. Keep the optics protected from dirt
and grease as they could become scratched.
Avoid running the image intensifier for long periods of time with a fixed image,
especially if it is bright, as there is a possibility that a permanent burnt-in image will
occur.
Excessive axial force will crack the screen pyroceram material used to seal the output
window into the image intensifier body. This renders the tube inoperable.
