L-740 ULTRA-PRECISION LEVELING LASER

L-740 Ultra-precision Leveling Laser

Description

The L-740 Ultra-Precision Leveling Laser provides an ultra-flat plane of light for quick, easy flatness and levelness measurements. It has an integrated precision leveling base with illuminated level vials accurate up to 1 arc second (0.00006"/ft. or 0.005 mm/M) and coarse and fine adjustments for pitch and roll.

The laser plane is flat to 0.5 arc second (0.00003"/ft. or 0.002 mm/M) in a 360º sweep and 0.25 arc sec (0.000015"/ft. or 0.0013 mm/M) in a 90º sweep. It has an operational range of 100 feet (30.5 meters) in radius.

The L-740 has coarse and fine Pitch and Roll adjustments to level the laser or to make it parallel to reference points. The diode laser is low power (less than 1 mW) and visible to the naked eye for easier setup.

Applications

  • For applications with tolerances of 0.00002"/ft. or 0.0017 mm/M or higher
