Principles of Operation:
LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Lasers radiate in a single wavelength, in one direction and in a straight line, and are detected by position sensing detectors (PSDs). PSDs detect and convert the center of energy of the laser spot into a calibrated digital reading for output to a hand-held readout or computer interface. Continuously sweeping laser planes are produced by bending a laser beam precisely 90° using an optical pentaprism. Hamar Laser applies a patented correction process to the pentaprisms to produce ultra-flat, continuously sweeping laser planes. Laser planes are used as references to measure the flatness, straightness or squareness of surfaces or machine axes. Three reference points are needed to make the laser plane parallel to a surface. However, only two points are needed to measure the straightness of an axis or a machine way. The laser plane is made parallel (“bucked in”) to a surface or line of motion by adjusting the pitch, roll or yaw of the laser base until the target displays the same reading at each reference point. The targets are then used to measure the deviation from the reference points up to 100 feet (30.5 meters) away from the laser. The data provided by the targets is automatically — and instantly — updated so the machine can be adjusted and the readout will show the movement. When it shows zero, it’s aligned! Hamar’s multi-plane lasers all feature laser planes that are orthogonal to each other and thus can be used to measure the squareness between surfaces or machine axes. In most cases with one setup, the laser can measure the squareness between all the axes of the machine tool.
Laser System Options:
Different applications require different levels of accuracy
which is why we developed two basic families of laser
alignment systems:
L-730 Series. tolerances are not as critical (e.g. simple fabrication alignment checks, etc.) L-740 Series. Ultra-precise, used for more demanding “mission critical” tasks (e.g. aligning complex machine tool geometry, etc.) Each family of lasers is available in single, dual and triple-plane versions. Many of the features and accessories within the two families are the same. The key difference is the degree of accuracy. For example, with the L-730 Series, laser plane flatness is accurate to 2 arc seconds (.00012"/ft or 0.01 mm/M). With the L-740 Series it’s a more stringent 0.5 arcsec (.00003"/ft or 0.0025 mm/M).
As would be expected, the tighter the tolerances and greater the accuracy level, the higher the price. Accordingly, the L-730 Series is an economical choice perfectly suitable for a wide
range of alignment applications that do not require the ultra-precision attainable in our L-740 Series lasers.
L-730 & L-740 Series Features:
• Live data output to measure - then fix - misalignment, in real time.
• Continuously sweeping laser planes with a range of 100' (30.5 m) in radius.
• Built-in squareness measuring capability of up to .00006"/ft or 0.005 mm/M (multi-plane lasers only).
• Multiple targets displayed simultaneously for faster alignment and setup.
• Collect flatness and straightness data simultaneously.
• Work up to 70% faster than interferometers, theodolites, transits and other conventional methods.
• Easy to learn how to use, simple to operate.
• Able to collect complete geometry data on most machines in under 90 minutes.

L-730 SERIES SYSTEMS :
High-Accuracy, Economically-Priced Laser Alignment Systems
The L-730 Series of single, dual and triple-plane laser systems adapts Hamar’s metrology innovations to applications with less stringent alignment requirements like fabrication alignment, textile roll alignment, wood-working, and the water-jet/laser-cutting machine tool industries. You get the benefits of our high-accuracy laser systems, at a price that is easier to justify.
