L-743 Ultra-Precision Triple Scan® Laser

L-743 Ultra-Precision Triple Scan® Laser

Description

Designed primarily for high-accuracy flatness, straightness and squareness measurements of machine tools, the L-743 Ultra-Precision Triple Scan® Laser has 3 auto-rotating laser planes, 2 vertical and 1 horizontal.  All 3 laser planes are flat within 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. The top-to-side and top-to-rear laser planes are perpendicular within 1 arc second (.00006 in./ft. or 0.005 mm/m).  The 2 side and rear laser planes are perpendicular to within 3 arc seconds.  It also features 3-arc-second illuminated level vials with optional L-740SP Split-Prism Upgrade to split-prism level vials accurate to 1 arc-second.

The laser is mounted on an adjustable base with coarse and fine pitch, roll and yaw adjustments, so that each 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.  It comes with a 10,000 mAh lithium ion rechargeable battery pack for up to 16 hours of continuous use with all 3 planes running.

Since the L-743 has 3 laser planes, multiple machine axes can be aligned and measured at the same time. In addition, laser planes make formerly difficult alignment measurements, like roll in horizontal and vertical machine axes, a very easy process.

The laser can project the measurement reference out to 100 feet (30.5 meters) in radius for each laser plane, so surfaces up to 200 feet (61 meters) can be measured in 1 setup.

Applications
