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).
A-1519-2.4ZB and A-1520-2.4ZB Single-Axis Wireless Targets
The A-1519-2.4ZB Single-Axis Wireless Target provides wireless
communication with a ±.5 in. (±12 mm) measuring range, an electronic
“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.
Applications
