CONTINUOUSLY SWEEPING LASERS: L-740 Ultra Series Lasers:

L-741 ULTRA-PRECISION LEVELSCAN® LASER

DESCRIPTION
The L-741 Ultra-Precision Levelscan® Laser adds a plumb laser beam to the L-740 style laser, offering the capability of checking and correcting squareness as well as flatness and straightness of vertical axes. This is the lowest cost alternative for machining center alignment.

The continuously rotating laser plane is flat to 0.5 an arc second (0.00003"/ft or 0.002 mm/M) in a 360º sweep and 0.16 arcsec (0.000015 in/ft or 0.001 mm/M) in a 90º sweep, and is square to the plumb beam to within 1 arc second (0.00006" or 0.005 mm/M). The Pitch/Roll base is equipped with backlit level vials that are accurate to 1 arc second. It has an operational range of 100 feet (30.5 meters) in radius. The laser mounts on a machine or stable base so that the laser plane can project the reference out to 100 feet in radius.

APPLICATIONS (for applications with tolerances of 0.00002"/ft or 0.0017 mm/M or higher)

• General machine leveling
• Checking squareness between machine axes
• Checking plumb of machine columns or fabrications
• Checking the flatness of almost any surface (squares, frames, ways, flanges, circles, etc.)
• Measuring and leveling 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
• Machining Centers (HBM, VBM, VTL, VMC, HMC, Gantries, Surface Grinders)
• Large Lathe Beds
• Presses

FEATURES

• Continuously sweeping diode laser plane with 100' (30.5 meters) radius operating range
• Setup in as little as 5 minutes
• Measures and corrects errors for both machine bed flatness and column squareness.
• Laser planes flat to 1/2 arc seconds (0.00003"/ft or 0.0025mm/M) in 360º sweep and 0.17 arc second (0.000015"/ft or 0.0013mm/M) in 90º sweep
• Plumb beam and continuously sweeping laser are square to within 1 arc second (0.00003"/ft or 0.0025 mm/M).
• Standard target: A-1519HR Single-Axis Wireless Target with 0.0001" (.0025 mm) resolution and 1" (25.4 mm) measuring range.
• Uses A-1520 Single-Axis Wireless Target with 0.00002" (0.0005 mm) resolution for higher accuracy applications.
• Targets provide live data display
• Laser and targets fit into a case into a small, portable shipping case
• Precision, backlit level vials in base accurate to 1 arcsec
• Uses A/C adapter or battery pack
• Instant on with virtually no warm up
• Uses Win95/98 Plane5 Software to quickly analyze and record (with A-1519 Target) flatness data
• Mounts on machine or stable base, such as the L-106, to project reference out to 100' (30.5 meters) in radius.
