Unsurpassed Plane Flatness
One of the critical components of any laser alignment system is the straightness or surface flatness of the laser beam or plane, as this is the reference from which the measurements are made.
The L-741 features the flattest laser plane in the world. Its continuously rotating laser plane is flat to 1/2 an arc second (0.00003"/ft or 0.002 mm/M) in a 360º sweep and 1/4 arcsec in a 90º sweep (0.000015"/ft or 0.001 mm/M).
100' Squareness Measuring Capability
It also features a plumb laser that is square to the laser plane to within 1 arc second (0.00006"/ft or 0.005 mm /M). This plumb laser can be projected out 100' (30.5 M), allowing squareness of even the tallest machine in the world to be easily checked. The L-741 laser alignment system also features 2 built-in level vials that are accurate to 1 arc second.
New Line of Wireless 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-741 laser alignment system utilizes our new line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to 0.00002" (0.0005 mm) resolution, large measuring ranges of up to 1" (25 mm) and an 2.4 GHz "Zigbee" radio communication with our R-1355-2.4ZB Ruggedized Nomad PDA, which can simultaneously display up to 5 targets.
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 alignment systems, the targets provide live alignment data so misalignment errors can be fixed without changing the setup!
