During the scanner operation the projector projects structured light to the object - coded lines and stripes. To ensure that the lines are sharp, the projector must be focused on the working distance of the scanner. By switching the mode "Lines and Stripes", adjust the focus of the projector, so that the lines on the calibration plate were as sharp as possible. Using the zoom ring set the minimum possible area of projector light. After changing the illumination area check the projector focus.

For other projectors, depending on the scan area, using the zoom ring you can select that area of light, in which all the plate will be lit, or use special lenses.
