Measurement optics for XL-80 Laser


    Measurement optics for XL-80 Laser

The same type of optics can be used for the XL-80 system, as the ML10. All measurements are interferometric and as a result of this, they use the traceable international standard wavelength of laser light.

The XL-80 optic system has various benefits that every user can enjoy. For example, it is interchangeable – meaning that it enables easy exchange for different measurements, without having to re-align th

e laser. Secondly, this measurement system also delivers convenience to the user because the moving optics have no cables to drag or snag.Lastly, this measurement system has quick acclimatisation; some competitor systems

Please note: For rotary axis calibration, please see the RX10 rotary axis calibrator section. Also, for other optical accessories to assist in set-up and measurement, please see the optics accessories section. use stainless steel optic housings and this system does not. Instead, it uses Renishaw's aluminium optics, which has a higher thermal conductivity level.

Linear measurement optics kit

Linear measurement is the most common form of measurement performed on a CMM machine.

Each linear measurement optics kit contains the following:

  • 1 linear interferometer
  • 2 linear retroreflectors and clamp screws
  • 2 alignment targets

Part number: A-8003-0440 Linear measurement optics kit.

Specification

Standard range 0 m - 40 m (0 in - 1600 in)
System accuracy (when used with XL-80 system) ±0.5 ppm (parts per million)
(when used with ML10 Gold Standard) ±0.7 ppm
(when used with ML10, pre-Gold Standard) ±1.1 ppm
Resolution 0.001 µm (0.1 µin)
Maximum velocity 4 m/s (9600 in/min)
Velocity measurement accuracy ±0.05%

For linear measurements over 40 m you will require the long range linear accessory kit

Angular measurement optics kit (standard)

These optics can measure maximum angular deflections of up to ±10° with resolution of 0.01 arc sec. As a result, angular pitch and yaw measurements can be taken.

Each angular measurement kit contains the following:

  • 1 angular retroreflector
  • 1 angular interferometer
  • 2 alignment targets
Axial range 0 m - 15 m (0 in - 590 in)
Angular measurement range ±175 mm/m (±10°)
Angular accuracy ±0.2% ±0.5 ±0.1M µm/m
(±0.2% ±0.1 ±0.007F arc sec)
Resolution 0.1 µm/m (0.01 arc sec)

Where:
% = percentage of displayed value
M = measurement distance in metres
F = measurement distance in feet

Angular measurement optics kit (calibrated)

These optics allow angular pitch and yaw measurements to be made. They also allow a lower measurement uncertainty than with standard optics.

Each calibrated angular measurement kit contains the following:

  • 1 angular retroreflector
  • 1 angular interferometer
  • 2 alignment targets
  • calibration certificate

Part number: A-8003-2532 Angular measurement optics – calibrated

Each retroreflector is supplied with a calibration certificate and marked with a calibration factor.

Specification as for standard angular optics but angular accuracy term is reduced from ±0.2% to ±0.04%, when the calibration factor is entered into LaserXL software.

These particular optics are available with steel housing, for greater thermal stability.

Linear and angular combination kit

This optics combination kit is a cost saving alternative for users who wish to perform both linear and angular measurements.

Each combination kit contains:

  • 1 linear retroreflector and clamp screws
  • 1 angular retroreflector
  • 1 angular interferometer
  • 3 alignment targets

Straightness measurement optics kit: 1 - 30 m axis length

These optics can be used to measure the horizontal straightness error in the linear axes, from 1 m up to 30 m in length. It must be used with the XL-80 laser system. This kit also enables measurement for the parallelism of axes.

Each long range straightness kit contains the following:
