Tilt of Laser Scan Line

7.1.1.
Maximum tilt between both ends of laser scan line.
Less than 1.2° upward tilt from the scan origin.
Maximum of 3.1 mm when measured at a point 150 mm away from the scan
origin. (The skew angle of this measurement was 0°.)
Measurement was done from the center of the scan line.

Curvature of Scan

7.1.2.
Maximum gap between the straight line connecting both ends of 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.
Measurement was done from the center of the scan line.
