L-740W Ultra-Precision Plumb Laser

L-740W Ultra-Precision Plumb Laser

Description

Designed primarily for high-accuracy vertical flatness and plumb measurements, the L-740W Ultra-Precision Plumb Laser has 1 vertical, auto-rotating laser plane that is flat within 0.5 arc seconds (.00003 in/ft or 0.0025 mm/m) in a 360º sweep and 0.25 arc seconds in a 90º sweep. It also features 3-arc-second illuminated level vials.

The laser is mounted on an adjustable base with coarse pitch, roll and yaw adjustments, so that the laser plane can project the measurement reference out to 100 feet (30.5 m) in radius in all directions. The laser is completely self-contained and can operate on battery or AC power.

Applications

Measuring and aligning:

  • The flatness and straightness of almost any vertical surface up to 100 feet (30.5 m) (squares, frames, ways, flanges, circles, etc.)
  • Plumbness of almost any surface (squares, frames, ways, flanges, circles, etc.)
  • The flatness/straightness of vertical surfaces
  • The straightness of vertically traversing axes of machine tools
  • The parallelism of vertical surfaces
  • Checking machine tool guideway twist in vertical axes and parallelism between vertical guideways
  • Measuring surfaces up to 200 feet (61 meters) long with 1 setup

Features

  • 1 continuously rotating, vertical laser plane with operational range of 100 feet (30.5 m) in radius.
  • High accuracy:  laser plane flat to 0.5 arc seconds (.00003 in/ft or 0.0025 mm/m) in a 360º sweep and 0.25 arc second in a 90º sweep
  • Includes Pitch/Roll/Yaw adjustment base with coarse and fine adjustments.
  • Standard illuminated levels accurate to 3 arc second (.00018 in/ft. or 0.015 mm/m).
  • Optional L-740SP high-accuracy, split-prism illuminated levels accurate to 1 arc second (.00006 in/ft. or 0.005 mm/m).
  • Uses A-1519-2.4ZB Single-Axis, Wireless Targets with ±.55 in. (±14 mm) measuring range and .00002 in (0.0005 mm) resolution.
  • Optional Ultra-Accuracy Target: A-1520-2.4ZB Single-Axis, Wireless Targets with ±.55 in. (±14 mm) measuring range and .00001 in (0.00025 mm) resolution.
  • Wireless targets provide real-time alignment data updating simultaneously.
  • Align and monitor multiple axes simultaneously using up to 99 targets at the same time.
  • Initial setup typically takes 10-20 minutes or less.   Transfer setups take 5-10 minutes.
  • Short warm-up
  • Optional Windows Win8/10 software for quickly recording and analyzing machine geometry data
  • Battery or AC powered
  • Laser and targets fit into portable shipping case
