This section describes best practices for lens focus adjustment of the 0.68:1 WQXGA lens 
(P/N: 125-103105-xx), the 0.80:1 WQXGA lens (PN: 125-105107-xx), and the 1.28 - 1.71:1 WQXGA
lens (P/N: 125-101103-xx).
1. Loosen the locking screw and the focusing screw.
2. Adjust the focusing screw for best focus in the image center.
3. 0.68:1 Lens Only: Loosen the field curvature locking screw and adjust the field curvature
focusing ring to sharpen the image corners.
