13.16 Using the close-up lens
13.16.1 General
If you need to look at small objects very close up, you can attach the close-up lens to the
infrared lens.
When the close-up lens is attached, the digital camera and the infrared camera do not
see the same scene. This means that functions that are based on content captured by
the digital camera cannot be used, e.g., continuous autofocus and some image modes.
When using the close-up lens, keep the following in mind. (For instructions, see section
13.16.2
Attaching the close-up lens , page 47.)
• For best performance, adjust the focus to infinity.
• The working distance for the close-up lens is 97 mm. (The working distance is the dis-
tance between the front of the lens and the closest surface of the object when the ob-
ject is in sharp focus.)
• You must activate the global parameter External IR window compensation .
• Only use the Thermal image mode.
• Deactivate continuous autofocus.
• Do not use the laser pointer.
Note The close-up lens can only be used with the infrared lens f = 36 mm (28°).
