Depth of Field for the MS720i Scanner
Through the glass at the front of the scanner, safe, low powered laser beams are projected in a complex pattern that resembles a spider web. Each of the five scan fields that generate the scan pattern extends to a range of 178mm (7.0"). The range begins 178mm (7.0") from the face of the scanner window and extends from the unit for a distance of 381mm (15.0") measured along the scanning beam at the center of each scan segment. This 178mm - 381mm (7" - 15") range is the depth of field for the MS720i scanner. (Refer to Figure
12)
The scan pattern is projected at a slight angle downward from the front of the scanner (approximately 10 degrees, overall). As the scan fields move outward, they expand. Like an image expands from a film projector as it moves toward the screen at a movie theater, the scan pattern projects out to a
