FLIR T8 Series User Manual

Achieving a good image
11
11.1 General
A good image depends on several different functions and settings, although some func-
tions and settings affect the image more than others.
These are the functions and settings that you need to experiment with:
• Adjusting the infrared camera focus.
• Adjusting the infrared image (automatically or manually).
• Selecting a suitable temperature range.
• Selecting a suitable color palette.
• Changing the measurement parameters.
• Performing a non-uniformity correction (NUC).
The following sections explain how to work with these functions and settings.
In some situations, you may also want to hide the overlay graphics for a better view.
11.2 Adjusting the infrared camera focus
It is very important to adjust the focus correctly. Incorrect focus adjustment affects how
the image modes work. It also affects the temperature measurement.
11.2.1 Manual focus
You can adjust the focus manually by rotating the focus ring. For more information, see
section 7.4.1 Manual focus.
11.2.2 Autofocus
You can autofocus the infrared camera by pushing the Autofocus button. For more infor-
mation, see section 7.4.2 Autofocus.
WARNING
When the camera is set to autofocusing with the laser method (Settings > Device settings > Focus > Au-
to focus >Laser), do not point the camera at the face of a person when you use the autofocus function.
The laser beam can cause eye irritation.
Note You can also assign the autofocus function to one of the programmable buttons.
For more information, see section 7.12 Programmable buttons.
11.2.3 Continuous autofocus
The infrared camera can be set up to perform continuous autofocusing. For more infor-
mation, see section 7.4.3 Continuous autofocus.
WARNING
Do not point the camera at the face of a person when the continuous autofocus function is on. The cam-
era uses laser distance measurements (that are continuous) for the focus adjustments. The laser beam
can cause eye irritation.
Note For large lenses that cover the laser transmitter and receiver, the laser functional-
ity is disabled. This means that continuous autofocus is not available.
11.3 Adjusting the infrared image
