Hamamatsu image intensifiers are warranted for one year from the date of delivery or 1000 hours of
actual operation, whichever comes first. This warranty is limited to repair or replacement of the
product. The warranty shall not apply to failure or defects caused by natural disasters, misused or
incorrect usage that exceeds the maximum allowable ratings.
When ordering, please double-check all detailed information.

Do not allow any object to make contact with the input or output window. The window might
become scratched.

marks adhere to the windows, use a soft cloth moistened with alcohol to wipe off the windows.
Never attempt cleaning any part of image intensifiers while it is in operation.

operation or storage.
Operating the image intensifiers while a bright light (e.g. room illumination) is striking the
photocathode, might seriously damage the photocathode.
The total amount of photocurrent charge that flows in the photocathode while light is incident
during operation has an inverse proportional effect on photocathode life. This means that the
amount of incident light should be kept as small as possible.
power supply made by another company, check before making connections to the image
intensifier, that the voltage appling to each electrode is correct.
If a voltage in excess of the maximum rating is applied even momentarily, the image intensifier
might fail and serious damage might occur.
supply module.
If the connections are incorrect, image intensifiers might be instantly damaged after the power is
turned on. Use high-voltage connectors or solder having a high breakdown voltage. When
soldering, provide sufficient insulation at the solder joint by using electrical insulation tape capable
of withstanding at least 10 kV or silicon rubber that hardens at room-temperature and withstands
at least 20 kV/mm.
