FLIR T530 / T540 Thermal Camera: Laser-Assisted Autofocus 

Hi Joli, Autofocus on the T5xx can either be used with the ‘thermal contrast’ or ‘laser’ option. If the laser is selected, then whatever the laser point strikes should be automatically focused (in theory). The thermal contrast option can be less effective if the temperature contrasts within the field of view are very low, potentially creating a more blurred image. If the thermal contrasts are good, then this should also focus the image clearly. It could be that there is an issue with the autofocus function, in which case it might need to be returned to service (a firmware update to the latest version can sometimes help resolve some issues).
