Focus Adjustment Tutorial for the Stock Lens of HUSKYLENS 2

Recently while using HUSKYLENS 2, I found that its stock native lens is not strictly fixed-focus. During manufacturing, DFRobot secures the lens with adhesive glue for fixation purposes only.

Accordingly, the factory lens can be modified to enable focus adjustment. The focusing range is limited, yet it suffices for most indoor scenarios.

1. Tool Preparation

Needle-nose pliers × 2 (small size preferred)

2. Loosen the Lens

Remove the lens from HUSKYLENS 2 and inspect it from the side.You will see the lens consists of two parts: the base inside the red frame and the focus ring within the blue frame.

Clamp these two parts separately with the two needle-nose pliers.

Hold the base firmly with one needle-nose plier, then twist the focus ring toward the lens using the other plier. Only loosen it slightly to break the glue bond.

Caution: Do not clamp the circuit board with the plier holding the base, otherwise the entire base may twist off and damage the lens.

Please note: Damage caused by improper operation or excessive force during twisting will void the DFRobot warranty.
