An Introduction to Laser Alignment
Laser alignment is a simple and extremely accurate method of aligning machinery. A laser alignment
system consists of a laser, a target (or targets), and some form of readout (either a hand-held device or a
computer interface). The laser provides an intense, narrow beam of light that stays focused over distances
of up to 100 ft. The target is a light sensitive cell that can detect the absolute center of the laser beam.
When the target is placed in the line of the laser beam, the readout displays the offset between the center
of the laser beam and the center of the target cell, either graphically, numerically, or both.
In addition to lasers that produce a straight beam of light, Hamar Laser also manufactures laser that
produce a continuously sweeping plane. These planes are produced by bending a laser beam precisely 90°
using an optical penta prism. A laser plane is used for alignment by making it parallel (or “bucked-in”) to
three reference points or a datum plane, and then using targets to measure deviations from those points.
Once the laser is bucked in, any point within range of the laser system (up to a 100 ft. radius (30.5 m))
can be aligned to the reference points.
Hamar Laser’s multi-plane lasers, such as the L-733 and L-743, generate up to three ultra-flat laser planes
(both horizontal and vertical) and can be used with multiple targets on multiple axes to check alignment.
In most cases, this requires only one setup procedure.
Laser “buck-in” refers to the adjustment of a laser plane or line to be parallel to the surface being
measured (a tabletop, a surface plate, or a way surface). Three points are required to buck-in a laser plane
to a reference surface. Two points are needed to buck-in a straight-line laser to a reference line (i.e.,
centerline). For most machining centers, the alignment process begins by bucking-in the laser to five
reference points, three points using the horizontal laser plane (usually on the machine’s table) and two
using one of the vertical planes. The two reference points for the vertical plane are usually chosen from
either the X or Y straightness motion of the machine. The horizontal plane is measured using vertically
mounted targets and the vertical plane uses horizontally mounted targets. The pitch, roll and yaw of the
laser planes are adjusted by using adjustment knobs built into the base of the laser.
After bucking in, the target is moved to various points along the surface where it measures deviation from
the laser reference plane. For squareness, a target is placed (usually horizontally) on one part of the
column and zeroed. The column is then traversed up or down and any deviation becomes a measurement
of squareness since the laser plane used for measuring is perpendicular to the reference laser plane.
This manual will cover the four procedures that are necessary to use a Hamar Laser alignment system:
1. Reading and Calibrating the Laser’s Precision Level vials
2. Three-Point Buck-In
3. Two-Point Buck-In
4. The NORMIN Procedure
Any alignment you perform consists of one or more of these procedures. This manual will explain these
procedures and how to perform them. By fully understanding them, you will be able to align virtually any
machine, transfer line or production setup. In addition, this manual contains several appendices that cover
more advanced procedures and alignments using older Hamar Laser products.

Alignment System Components
Lasers
The L-743 Ultra-Precision Triple Scan®Laser
The L-743 Ultra-Precision Triple Scan®Laser is Hamar Laser’s most
versatile and powerful machine tool alignment laser. It has been
designed specifically for 3-5-axis machining centers to measure and
correct machine geometry. In most cases, all it takes is one setup to
measure flatness, straightness, parallelism and squareness of the main
axes of most typical machining centers.
Since the system provides live measurements, any errors that are
found can be fixed with the same setup. The laser mounts on a
machine or stable base so that the laser plane can project the
measurement reference out to 100 ft. (30.5 m) in radius for each laser
plane.

Targets
Note: The targets discussed in this section can easily be converted to a height gage, as the center of the target cell
is set to a known distance from the bottom of the target housing. By attaching precision spacers to the base of the
target, the exact dimension from the laser plane to the measured surface can be obtained. These precision spacers
are available in 1 in. (25.4 mm), 2 in. (51 mm), 3 in. (76 mm) and 6 in. (154 mm) sizes, all of which are accurate to
.0003 in. (0.008 mm).

“zero” function and an indoor operating range of 100 ft. (30.5 m) from
laser to target. The targets feature a resolution of .00002 in. (0.0005 mm),
a fully linearized, position-sensitive detector with automatic background-
light correction, automatic on/off operation (laser turns it on), and an on-
target indicator.
The A-1519 is linearized to within ±.00015 in. (±0.0038 mm) over the
useful range of the target. These targets can easily be converted to a
height gage, as the center of the target has been set to a tightly controlled
dimension. Attach the 2.565 in. (65.15 mm) spacer to the base of the
target and the exact dimension from laser plane to the measured surface
can be obtained. Optional precision spacers are available in 1 in. (25.4
mm), 2 in. (51 mm), 3 in. (76 mm) and 6 in. (154 mm) sizes, all of which
are accurate to .0003 in. (.008 mm).
For applications where greater accuracy is needed, such as surface plates,
the A-1520 has a resolution of .00001 in. (0.25 microns) and is linearized
to within ± .00006 in. (0.0015 mm) over 80% of the sensor area. It has a
.250 in. (6.35 mm) measuring range and all the other features of the A-
1519.

Readouts
The R-1357-2.4ZB Wireless, Ruggedized PDA Data Receiver with Read16 Android
Software
The R-1357-2.4ZB offers hand-held convenience, wireless
communication via the ZigBee Networking protocol, and multi-
purpose Read16 Android Software. The R-1357-2.4ZB uses a
rugged, IP 68 Android PDA combined with Read16
Android Software to display the data for our A-1519/A-1520
wireless targets and any of our L-730-740 Series rotating lasers.
When combined with our R-1307-2.4ZB Readout, it can also
display the data for our 2-axis targets. Data can be displayed for up
to five single-axis targets and two 2-axis targets.
The radios employ a frequency-hopping protocol to avoid
interference with other radio devices that might be operating at the
same frequency. The radio allows the selection of different system
IDs so that two or more systems can work in the same area and
will not interfere with each other.
Features of the R-1357-2.4ZB
•A rugged PDA with a sealed wireless transmitter and an IP 68 environmental rating that can survive
water up to three feet with no harm.
•Long battery life of 10½ hours with a 4½ hour recharge time.
•Read16 Software pre-installed for basic alignment functions.
•Data display for up to five wireless targets.
•Wireless range of up to 133 feet.
•Compatibility with any of Hamar Laser’s continuously rotating lasers.

The R-1356-2.4ZB Wireless, Ruggedized PDA Readout with Read15 Software
The R-1356 is an innovative readout that comes with Hamar Laser’s Read15
alignment software preinstalled on a ruggedized personal digital assistant
(PDA). The R-1356 operates with both the A-1519-2.4ZB and A-1520-2.4ZB
radio wireless targets and any continuously rotating laser. The readout can
display data from up to eight wireless targets and has a wireless range of up to
133 ft., eliminating cabling and multiple readouts. It allows a user to perform
many alignment functions with the convenience and portability of a handheld
computer. The display screen shows a measurement value for each of the
connected targets (with the numbers corresponding to the labels on the
targets). Each numeric value represents the position of the laser plane relative
to the target centerline. A positive reading indicates that target is above the
laser plane; a negative reading indicates that the target is below the laser
plane.
The R-1356-2.4ZB can toggle between Absolute (indicating exactly where
the laser plane hits the target cell) and Relative modes. In Relative mode, the
readout shows the measurement relative to the user-determined zero point. It
also shows a display of the difference between two target measurements, a
very useful feature for "buck-in," roll alignment and angular measurements,
and a graphical display of each target's position relative to the laser plane.
Features
•A rugged PDA with a sealed wireless transmitter and an IP 67
environmental rating that can survive water up to 3 ft. with no harm.
•Long battery life (15 hours), with a 2.5 hour recharge time.
•Read15 software pre-installed for basic alignment functions.
•Data display for up to 8 wireless targets.

Computer Interface
A-910-2.4ZB Wireless Computer Interface
The A-910-2.4ZB computer interface is a small, compact USB dongle wireless
receiver that communicates with up to 99 2.4GHz ZigBee® targets. Power is
supplied by a laptop computer’s USB port. The A-910-2.4ZB allows a data link
for Hamar Laser software other than Read15, which is used on the R-1356. Both
the R-1356 and the A-910-2.4ZB Computer Interface can be used in the same
area when one is configured in Listen Mode and the other in Master Mode (the
unit in Master Mode controls the send/receive commands to get the targets to
send their data). System IDs can be changed in the software (see Page 88).

Preparing to Perform an Alignment
Defining Flatness and Level
“Measuring level” usually means measuring flatness using a level. The proper definition of flatness is: a
surface is said to be flat to a tolerance if all the points on that surface fall within two parallel lines, or
planes, separated by the tolerance value.
For example, if the flatness tolerance is .0030 in. TIR, then all the points must deviate from zero by no
more than ± .0015 in.
There are two ways to measure flatness using our lasers:
•Level the laser, using our high-accuracy, built-in level vials, and measure the surface relative to the
level laser plane
•Use three reference points on the surface, align the laser (“bucking-in”) to those points and measure
the flatness relative to those three points.
After recording the data, it is best to use our Plane5 Software to analyze the data using the Least-Squares,
Best-Fit algorithm, which removes any slope error if the laser plane is not parallel to the surface, or if the
surface is not level but the laser plane is.
Setting Up the Targets
Targets may be mounted to a surface via the magnetic base. Target operation is automatic, with no
switches, wires or connectors, and flashing indicators provide immediate “off target” status. The wireless
targets transmit data every time the laser beam scans across the position detector and a new reading is
obtained. They rely on the laser to set the pace of the data transmission.
Please Note!
Our level vials are designed to be calibrated by the customer. We cannot guarantee that the level
vials are calibrated when you receive the equipment because of movement during shipping. Please
follow the procedure below specific to the level vials on your laser.

Using the Control Panel
Figure 6 shows the control panel for the L-743 and L-733
lasers, including the locations of:
•The battery pack/AC adapter connection
•The power switches and POWER ON indicator for the
laser
•The power switches for the individual scanners
•The light for the precision level vials
Note: As of January 1, 2014, the level light switch has
been modified. The level light now stays on permanently to
increase stability and allow the laser to warm up faster.
•The rotation speed buttons. These controls slow the
scanner spin until you can see the laser beam pass over the
target (the farther away the target is located, the slower the
turret must spin). Select SLOW, MEDIUM, or FAST.
Figure 7 shows control panels for the L-742 and L-732 lasers,
both the “Wall-Wall” configuration with two vertical laser
planes, and the “Wall-Ceiling” configuration, with one
vertical laser plane and one horizontal laser plane. Also
shown is the front panel for the L-730/L-740.

The Precision Level Vials
Reading the Precision Level Vials
Secure the laser base to a metal surface by
turning the locking magnetic base ON. Once
the laser is in position, power it on and use the
adjustment knobs to bring the bubbles to the
center of both vials (see Figure 8).
When both the PITCH and ROLL vials are
reading level, the laser plane will be level to
earth to within .00016 in/ft (0.015 mm/m) for
the Precision Levels and .00006 in/ft (0.005
mm/m) for the Split-Prism Levels
Reading the L-740SP Split-Prism
Level Vials
Once the laser unit is in position on the base,
power it on and use the coarse alignment
micrometers to bring the bubbles to the
center of the level window.
When the bubbles are close to the center, use
the fine adjustment micrometers to align the
bubble halves to each other in the viewing
prism window (see Figure 9). When both the
PITCH and ROLL axis vials are reading
level, a level beam can be scanned at 360
degrees with a .0003 in. (0.0075 mm)
deviation per 10 ft. (3 m).
