You can focus Pixy by turning the lens clockwise or counter-clockwise. Do this while looking at the PixyMon window in “Raw” mode (click on the Raw icon). If turning the lens is difficult, you may need to loosen the set screw.

After you achieve a good focus, tighten the set screw so the lens will stay focused.

Pixy's lens will focus on objects that are very close, even less than an 1/2 inch from the lens. However, most users prefer to operate Pixy with its lens focus set to infinity, which (for Pixy's lens) means that any object that is 2 inches or farther from the lens will be in focus. (note: we set the focus to infinity before shipping each Pixy, although it may shift slightly in transit).
