6.2. Curvature of Scan
Maximum gap between the straight line connecting both ends of the laser scan line and the actual
laser scan line: Less than 1.27° curvature from the scan origin.
Maximum of 3.3 mm curvature when measured at a point 150 mm away from the scan origin. (The
skew angle of this measurement was zero degrees.)
Measurement was done from the center of scan line.
