L-732 Precision Dual Scan® Laser Alignment System

Flatness, straightness, squareness, leveling alignment laser

Primarily designed for roll alignment and other similar alignment applications that do not require the exacting tolerances of the L-742 Ultra-Precsion Laser, the L-732 Precision Dual Scan® Laser System offers 2 automatically rotating laser planes that can be configured by the factory to have either 2 vertical planes, or 1 horizontal and 1 vertical laser plane. Affordable, yet powerful, the L-732 not only MEASURES but it also FIXES alignment errors in a fraction of the time needed with conventional methods.

2 Arc Second Accuracy


One of the critical components of any laser system is the straightness or flatness of the laser beam or plane, as this is the reference from which the measurements are made.

The L-732's laser planes are flat and square to 2 arc seconds (0.00012"/ft or 0.01 mm/M). It comes with a pitch, roll and yaw adjustment base, for setting the laser planes parallel to reference points, 2-arc-second level vials and a powerful magnet for maximum stability.

Two Configurations for Many Different Applications

With two continuously sweeping, ultra-flat, orthogonal laser planes, the L-732 Dual Scan® Laser System is ideally suited for a whole host of alignment applications. The L-732 comes in 2 configurations. The standard L-732 has 1 horizontal laser plane and 1 vertical laser plane. It is used for measuring flatness straightness and squareness on machining centers, gantries and roll forming machines. The L-732WW has 2 vertical laser planes and is used primarily for aligning the horizontal roll parallelism of printing presses, paper mills, films lines and other roll alignment applications.

New Large-Range Targets

Another critical component of laser alignment systems is the resolution of the targets. This determines how close the measurements can be made.

The L-732 system utilizes our new line of Extended-Range Universal Scan Targets ( A-1532 and A-1533) that feature: 0.001" (0.025 mm) resolution, large measuring ranges of up to 3" (75 mm) and built-in readouts. These targets are all powered by rechargeable batteries, are lightweight and can be used as digital height gages when used with precision inserts. And like all Hamar laser systems, the targets provide live alignment data so misalignment errors can be fixed without changing the setup!


Alignment Applications

For alignments with tolerances of 0.00015"/ft or (0.01 mm/M) or greater, the L-732 can quickly measure and correct machine geometry with minimal setup in the following applications:

  • Water-jet cutting machines
  • Laser-cutting machine
  • Normal or blown-film lines (roll alignment)
  • Rubber (roll alignment)
  • Steel (roll alignment)
  • Textiles (roll alignment)
  • Saw Mills
  • Leveling almost any surface (squares, frames, ways, flanges, circles, etc.)
  • Measuring and aligning:
    • The flatness of almost any vertical surface (squares, frames, ways, flanges, circles, etc.)
    • The squareness of any 2 vertical surfaces
    • The flatness and straightness of vertical surfaces
    • The straightness of horizontally and vertically traversing axes
    • The parallelism of vertical or horizontal surfaces, even if those surfaces are 100 feet (30.5 meters apart)
  • Checking plumb of a vertical surface up to 100 feet (30.5 meters)
  • Checking way twist and parallelism between vertical surfaces
  • Measuring surfaces up to 200 feet (61 meters) long with 1 setup

Compatible with New Wireless Targets

The L-732 can also be used with our line of wireless targets (A-1519-2.4ZB, and A-1520-2.4ZB) that communicate with a Ruggedized Nomad PDA and A-910-2.4ZB radio receiver for a laptop. For wireless recording and analyzing alignment data, our color, 3-D flatness and squareness analysis software, Plane5, simplifies and streamlines the data analysis process. It can measure up to 7 different surfaces in one project setup file and present a color, 3-D graph of the flatness and squareness analysis for each surface.
