Introduction
Cleaning optics
Identifying debris
Debris on the image sensor or optical components appears as a darkened area
or smudge on a camera image. Do not confuse this with a pixel defect which
appears as a distinct point.
Locating debris
First determine whether the debris is on the sensor glass, IR filter (if used), or
lens. The farther away the debris is from the sensor, the blurrier the debris
appears on a camera image.
Stream a live image from the camera using a uniform target, such as a piece of
paper. To determine if the debris is on the camera lens, rotate the lens indepen-
dent of the camera. If the spot moves, the debris is on the lens. Otherwise, the
debris is on the IR filter (if used) or sensor glass.
Caution

Cleaning.
This product can be damaged by some volatile cleaning
agents. Avoid cleaning the image sensor unless absolutely
necessary. Please see instructions on optics cleaning in
this document.
Caution

Do not exceed environmental specifications.
See environmental specifications limits in the Specifications
section of this document. Special care must be taken to
maintain a reasonable operating temperature. If the camera
is operated in temperatures higher than the specified range,
the camera should be mounted on a heat sink.
Caution

AVT does not warranty against any physical damage to
the sensor/filter/protection glass or lenses. Use
utmost care when cleaning optical components.
Caution

Do not touch any optics with fingers. Oil from fingers
can damage fragile optical coatings.
