The L-742 Ultra-Precision Dual Scan® Laser offers 2 automatically rotating laser planes. It has been designed specifically for roll alignment applications. It is a very affordable yet powerful tool to not only MEASURE but also FIX roll misalignment on almost any kind of film line or process mill, all in a fraction of the time needed with conventional methods.

2 continuously rotating laser planes with operational range o 100' (30.5 meters) in radius.
Laser planes flat to 1/2 arc seconds (0.00003"/ft or 0.0025 mm/M) in 180º sweep and 1/4 arc second (0.000015"/ft or 0.001 mm/M) in 90º sweep.
Planes are mutually square to 1 arc second (0.00006"/ft or 0.005 mm/M).
Includes Pitch/Roll/Yaw base with coarse and fine adjustments.
