Heat Sinks

FLIR A68/A38 series cameras are designed to optimally transfer internal component
heat to the outer metallic body. If the camera is free standing (that is, not mounted) it
will be warm to the touch.
Basic heat management is achieved by mounting the camera onto a metal structure via
its mounting screw holes.
Teledyne FLIR recommends that the FLIR A68/A38 series camera be mounted using
heat sinks to optimize shutterless operation. Refer to the Mechanical Specifications
section for information on the exact size and position of the camera mounting holes.
For radiometric operation (where the camera is expected to measure the temperature
of objects in the scene), additional care should be taken to provide a stable operating
temperature; please refer to the section

Adjusting the Lens Focus

The FLIR A68/A38 series cameras lenses are shipped with a factory calibrated setting
nominally focused to infinity. If necessary, the user can adjust the lens manually to
achieve the required focus. When the required focus is achieved, the lens position can
be secured by tightening the lens lockdown screws (with a 1.5mm hex driver).
Note: To avoid overtightening the lens screws use a nominal torque of
1.5 in-lbs.
