Removing an infrared lens
4.3.2.2
Note
•
The detector is a very sensitive sensor. It must not be directed towards strong visible
or sun light.
•
Do not touch the lens surface when you install the lens. If this happens, clean the
lens accordingly to the instructions in section 9.1.2 on page 52.
•
Lenses can be heavy. Some lenses weight several hundred grams. Be careful not to
be surprised by its weight.
•
When you have removed the infrared lens, put the lens caps on the lens to protect it
from dust and fingerprints.
Procedure
Follow the procedure to remove an infrared lens

Using an Extension ring
4.3.2.5
Note
•
The detector is a very sensitive sensor. It must not be directed towards strong visible

Do not touch the lens surface when you install the lens. If this happens, clean the

Using an extension ring requires the user to have strong understanding of the
radiometric consequences and induced measurement errors. Infrared Training
Center (ITC) offers courses and training. For more information about obtaining the
training you require, contact your FLIR sales representative or ITC at
www.infraredtraining.com
Extension rings can be introduced between the camera and the infrared lens in order to
change the minimum focus distance and thus the field of view of the camera. It is possible to
add several extension rings at the same time.
Please refer to the specification sheet of your infrared lens for available extension ring
dimensions and corresponding performances.
When an extension ring is used, the identification of the measurement configuration to be
used by the camera is done manually. Please refer to §4.4.4.
