A-517 SINGLE-AXIS SWEEP TARGET AND STAND

DESCRIPTION

The A-517 Single-Axis Sweep Target is primarily used for measuring straightness and flatness with all Hamar Laser's continuously rotating lasers to .0001" (.0025 mm) tolerances. The target head is designed to mount on a magnetic stand, using three variable length extension rods. It has a micrometer to mechanically adjust the center of the target and can swivel on its base 360 degrees without varying the measurement by more than .0001" (.0025 mm).

APPLICATIONS

  • Flatness, levelness, straightness, squareness and parallelism of machine tools and roll alignments. For use with L-719, L-720, L-720M, L-722, L-723 lasers.

FEATURES

  • Instantly generates flatness and straightness measurements to .0001" (.0025 mm) tolerances.
  • Incorporates a swivel mount that allows it to rotate ( .0001" tolerance) to face the laser without having to move the magnetic base.
  • The three extension rods included with the A-517 are 2.25"(57.2 mm), 4.0" (100.1 mm) and 6.25" (157.8 mm) in length. They can be combined to meet various elevation requirements up to 12.5" (317.5 mm).
  • The target incorporates a micrometer with 0.5" (12.7 mm) of travel, used to make fine adjustments to the elevation or to verify target calibration.
  • The magnetic stand has a "v-block" mounting surface that can be mounted on flat or cylindrical surfaces. A detachable bubble level is used to cross-level the unit on non-flat surfaces, like rolls. The level can be re-positioned on the base to match the target orientation.
  • The A-517 is used primarily with the R-308 readouts and can be used with the R-355 Computer Interfaces (requires T-251 Target Preamp).

A-1519/A-1520 SINGLE-AXIS WIRELESS TARGETS

View Datasheet [PDF, 524K]

DESCRIPTION

The A-1519 and A-1519HR Single-Axis Wireless Targets provide wireless communication with a 1-inch (25.4 mm) measuring range, an electronic "zero" function and an operating range of 100 feet (30.5 meters) from laser to target. They feature 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 0.0005" (.013 mm) over the useful range of the target. The A-1519HR is linearized to within 0.0001" (0.0025 mm).

The targets are powered by rechargeable, lithium-ion batteries and 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" (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" (25 mm), 2" (50 mm), 3" (75 mm) and 6" (150 mm) sizes, all of which are accurate to .0001" (.0025 mm).

For applications where greater accuracy is needed, such as surface plates, the A-1520 has a resolution of 0.00002" (.0005 mm) and is linearized to within 0.00004" (0.001 mm). It has a .250" (6.35 mm) measuring range and all the other features of the A-1519.

APPLICATIONS

  • Flatness, levelness, straightness, squareness and parallelism of machine tools, roll alignment applications, and surface plates (A-1520). Primarily for use with L-740, L-741, L-742 and L-743. Can also be used withL-719, L-720, L-722, L-723, L-730, L-731, L-732, and L-733.

FEATURES

  • Wireless infrared communication with a range of up to 100 feet (30.5 meters) with direct line of sight.
  • The A-1519 has a resolution of .0005" (0.013 mm), and the A-1519 HR has a resolution of .0001" (0.0025 mm). The A-1520 has a resolution of 0.00002" (0.0005 mm).
  • The A-1519 is linearized to within: 0.0005" (0.013 mm). The A-1519HR is linearized to within 0.0001" (0.0025mm). The A-1520 is linearized to within 0.00004" (0.001 mm).
  • A-1519 and A-1519HR have a 1-inch (25.4 mm) measuring range. The A-1520 has a 0.250" measuring range (6.35 mm).
  • Automatic background-light correction for added accuracy.
  • Can easily be converted to a height gage by attaching optional precision spacers.
  • Automatic on/off operation with no switches, wires or connections.
  • Flashing target indicators provide immediate "off-target" status.

A-1531/A-1532/A-1533 EXTENDED-RANGE UNIVERSAL SCAN TARGETS

View Data Sheet (coming soon)

DESCRIPTION

Our new line of low-cost, medium-resolution, extended-range targets (A-1531, A-1532 and A-1533) have been designed for optics users who do not require the ultra accuracy of our machine-tool alignment targets but desire the added accuracy and greater timesavings of our new line of lasers (L-730 Series).

Designed to work with all of Hamar Laser Instruments' continuously sweeping lasers, most sweeping lasers from other manufacturers, and with theodolites scales for dimensional measurement, these targets are well suited for indoor construction work or any applications that require measurement of flatness, levelness, straightness, squareness and parallelism.

The targets all have built-in measurement displays and a measurment capability of .001" (.025 mm). The A-1533 features a large-number, rotating display for viewing the measurements from behind or to the side of the target.

The targets features measuring ranges of up to 3" (76 mm) with selectable resolutions of 0.001" (0.02 mm), 0.005" (0.1 mm) and 0.010" (0.2 mm). They can also easily be converted to a height gage, as the center of the target has been set to a tightly controlled dimension. Attach a precision 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" (25 mm), 2" (50 mm), 3" (75 mm) and 6" (150 mm) sizes, all of which are accurate to .0001" (.0025 mm). The target is powered by a rechargeable, lithium-ion battery.

APPLICATIONS

  • Flatness, levelness, straightness, squareness and parallelism of machine tools, and roll alignment applications with resolution requirements of 0.001" (0.01 mm) or higher. For use with L-730, L-731, L-732 and L-733 lasers.

FEATURES

  • Large measuring range - 1.5" (38 mm) to 3" (76 mm)
  • A-1533's display rotates 355 degrees and has large numbers for long-distance applications
  • Multiple display modes
    - ZERO - zero at any point on the full range of the target,
    - TGT CTR - provides the reading relative to mechanical target center, and
    - BASE - provide the actual dimension from the base of the target to the laser beam.
  • Automatic on/off operation - target activates when the laser beam sweeps across the target cell.
  • Optional bracket for use with theodolite scales.
  • Display indicators provide immediate "off target" status.
  • English and metric units switch
  • Powered by a rechargeable lithium ion battery for long life and usage.
