L-740 ULTRA-PRECISION LEVELSCAN® LASER

DESCRIPTION
The L-740 Ultra-Precision Levelscan® 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 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 accurate 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. A three-position switch (LASER & SCAN, LASER ONLY, and OFF) controls the laser beam, and the level vials are illuminated for easy reading. 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)

  • General machine leveling
  • Checking the flatness of almost any surface (squares, frames, ways, flanges, circles, etc.)
  • Measuring machine beds and ways, large bearing surfaces, and fabrications
  • Checking way twist and parallelism between horizontal surfaces
  • Aerospace tooling leveling/floor alignment
  • Turbine split-joint leveling/measuring
  • Continuous casters
  • Antenna arrays
  • Large Lathe Beds
  • Surface Plate Calibration

FEATURES

  • Continuously rotating diode laser with 100' (30.5 meters) radius operating range.
  • Instant on with virtually no warm up.
  • Setup in as little as 10 minutes.
  • Laser plane flat to 0.5 arcsec (0.00003"/ft or 0.0025 mm/M) in 360º sweep and 0.16 arc seconds (0.000015"/ft or 0.0013 mm/M) in 90º sweep.
