The focus-tool accessory, allows any FLIR Boson lens which cannot be focused by hand to be focused by engaging the appropriate slots on the lens barrel such that it can be rotated inside the lens flange. (The focus tool has been properly sized such that no vignetting results when it engages the slots on the lens barrel.) Note that lens configurations with focal length >25mm do not require a focus tool since focus is achieved by simply turning the outer barrel of the lens assembly by hand.
This product is NOT compatible with the following FLIR Boson Thermal Imagers:
