How do you focus the objective lens on a high-definition thermal imager?


① Before focusing the objective lens, please ensure that the eyepiece focus (diopter adjustment) has been completed.

② Align the objective lens with the target you wish to observe, and adjust the focus knob until the image of the target is clearly in focus.

③ Thermal imaging systems have a minimum focusing distance; it is normal for certain objectives to be unable to clearly image targets within 3 meters. In general, the objective lens is focused at infinity.

Note: Glass is opaque.
