Hamar Laser’s L-740 Ultra-Precision Leveling Laser System is the most accurate and easy-to-use leveling, surface flatness and straightness measurement system on the market today. It features an automatically rotating laser plane that is the flattest in the world, large-range, wireless targets and built-in 1 arc second level vials. Continuously rotating laser planes and the capability to use multiple sensors at the same time let you level machinery 2 to 3 times faster than laser transits, theodolites or levels.

The L-740 Laser Leveling and Alignment System is the most accurate and easy-to-use surface flatness and straightness measurement system on the market today. It features a continously rotating laser plane that is the flattest in the world, wireless targets and built-in 1-arc second level vials. Continuously rotating laser planes and the ability to use multiple sensors at the same time means the L-740 can level machinery 2 to 3 times faster than laser transits, theodolites or levels.
One of the critical components of any laser leveling and alignment 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-740’s continuously rotating laser plane is flat to 1/2 an arc second (0.00003 in/ft or 0.0025 mm/m) in a 360º sweep and 1/4 arc sec in a 90º sweep (0.000015 in/ft or 0.001 mm/m).
Another critical component of flatness or straightness measurements is the resolution laser beam detector. This determines how close the measurements can be made.
The L-740 system uses our line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to 0.00002 in. (0.0005 mm) resolution, large measuring ranges of up to 1 in. (25 mm) and 2.4 GHz “Zigbee” radio wireless communication with our R-1356-2.4ZB PDA Readout, which can simultaneously display up to 5 targets.
These lightweight targets are all powered by rechargeable batteries 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!
The L-740’s applications include:
For wireless recording and analyzing alignment data, our Plane5 3-D flatness and squareness analysis software simplifies and streamlines the data analysis process. It can record flatness measurements in up to 7 different surfaces in one project setup file and presents a color, 3-D graph of the flatness and squareness analysis for each surface.
Taking measurements is as easy as simply leveling the laser, placing a target on one point of the surface and zeroing it. You are now set up to take flatness or straightness measurements. Performing alignments is as simple as placing the target over an adjustment point and turning the bolts while watching the wireless, hand-held readout update the readings automatically. Laser transits and theodolites require at least 2 operators to level machinery while our lasers require only one technician.
