The On-Trak OT-4040LL is a precision laser alignment system engineered for X-Y deviation measurement over extended distances in demanding industrial environments. It replaces traditional optical alignment methods with superior speed, accuracy, and operational ease. The system delivers measurement capability to 300 feet (100 meters) with 0.001-inch (0.01 mm) resolution and ±0.002-inch (0.05 mm) accuracy for both beam centration and target centering.
