Hardware Overview
The T-1297 3-Axis Wireless Spindle & Straightness Target
Hamar Laser’s T-1297 3-Axis Wireless Spindle & Straightness Target is designed work with our L-703S Spindle &
Straightness Laser. With Bluetooth communication and multiple measuring axes, the T-1297 target is a multi-purpose
target that can be used for many different applications.
• Offers 2 measurement modes:

Center Mode - 2-axis center measurement for use with the
L-702SP’s through-beam.

Flatness (Scan) Mode - single-axis flatness measurement for use with our
series of auto-rotating lasers (L-730/L-740/\ L-702SP) in Scan Mode.
• PSD (Position Sensing Detector) Size:

.39 x .39 in. (10x10 mm) PSD
• Resolution (2 axis & 1 axis): .00001 in. (0.00025 mm)
•
Wireless communication via Bluetooth Class 1 radio with 100 ft. (30 m) of
communication range.
•
Accuracy: error is < 0.25% of the measurement
•
PSD concentric to the mounting stud to < .0003 in. (0.008 mm).
•
The T-1297 is designed so the measuring plane of the target is right at the face
plate of mounting stud, so when used with the A-1297 High-Accuracy Flatness-
Measuring Base, it achieves the highest accuracy possible.
•
Accelerometer rotation axis (3
rd
axis) helps to orient the PSD sensor axes to the alignment axes of the spindle.
•
Lithium polymer rechargeable battery with 14 hours of battery life.
How to Use the T-1297 Targets
The T-1297 Targets are designed for use with the L-703S in Double-Blink Mode (center/angular measurements) or
Scanning Beam Mode (flatness measurements using one of our scanning laser plane lasers). The targets have a .4995 in.
(12.69 mm) mounting stud for mounting spindles and fixtures, such as the A-1297 High-Accuracy Flatness Measuring
Base.
T-1297 Center Mode
This is the default mode when the target is turned on. It is recommended while in Center Mode to use the light/dust
shield, which is held in place with magnets. While in this mode, the values shown in Plane6 Software displays show the
center (offset) values of the target’s mounting stud relative to the laser beam. It follows the same sign convention as
