How does the long EFL with large optics capabilities affect the DRI?

Update Time:2022/9/6

The focal length determines the field of view (FOV) of the thermal imaging camera. The longer the focal length, the smaller the FOV, which translates into more pixels across a target at a fixed range (meaning, the target angle divided by the IFOV angle).
