Products \ Laser Calibration & Telescoping ballbar \ XL-80 \ Measurement optics for XL-80

The same optics can be used with XL-80 or ML10 systems, ensuring consistency of measurement set-ups and procedures. All measurements are interferometric and therefore use the traceable international standard wavelength of laser light, allowing you to have total confidence in the results.

For rotary axis calibration, please see XR20-W rotary axis calibrator section and for other optical accessories to assist in set-up and measurement, please see the optics accessories section.

Interchangeable - The unique design of linear, angular and straightness optics enables easy interchange for different measurements, without having to re-align the laser.

Convenient - Moving optics have no cables to drag or snag, for best accuracy and convenience.

Low mass aluminium optics - The optics are manufactured in aluminium, therefore the optics' low mass is especially relevant if measuring pitch errors on horizontal arm CMMs and for dynamic measurements.

Quick acclimatisation - Some competitor systems use stainless steel optic housings. These are much heavier than Renishaw's aluminium optics and have a lower thermal conductivity, therefore taking longer to acclimatise to the shop environment.

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

Each linear measurement optics kit contains:

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

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

Specification

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

These optics allow angular pitch and yaw measurements to be made. Can measure maximum angular deflections of up to ±10° with resolution of 0.01 arc sec.

Each angular measurement kit contains:

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

Part number: A-8003-0441  Angular measurement optics

Specification

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

These optics allow angular pitch and yaw measurements to be made with a lower measurement uncertainty than with standard optics.  Each retroreflector is supplied with a calibration certificate and marked with a calibration factor. 

Each calibrated angular measurement kit contains:

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

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

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.

Also available with steel housings for greater thermal stability.

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

Part number: A-8003-2774  Linear and angular optics combination kit

These optics allow the measurement of horizontal straightness error in linear axes up to 4 m in length to be made. They also enable axis parallelism to be measured.

Each short range straightness kit contains:

• 1 straightness interferometer
• 1 straightness reflector

Part number: A-8003-0443  Straightness optics - short range

Specification

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

May require Universal (straightness) shutter or straightness accessory kit, depending upon application (see optics accessories section)

These optics can be used to measure the horizontal straightness error in linear axes from 1 m up to 30 m in length when using the XL-80 laser system. They also enable measurement for parallelism of axes.

Each long range straightness kit contains:

• 1 straightness interferometer
• 1 straightness retroreflector
• 2 alignment targets

Part number: A-8003-0444  Straightness optics - long range

Specification

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

* subject to environmental conditions

May require Universal (straightness) shutter or straightness accessory kit, depending upon application (see optics accessories section)

These optics determine the out-of-squareness of two nominally orthogonal axes, by comparing their straightness slope values which are referenced via the optical square.

Note:
A straightness measurement optics kit  and straightness accessory kit are also required to perform squareness measurements.

Each squareness measurement optics kit contains:

• 1 optical square and clamp screws
• 1 bracket (for adjustable turning mirror)

Part number: A-8003-0665  Squareness measurement optics

Specification

Where:
M = measurement distance in metres
F = measurement distance in feet

The flatness mirrors not only rotate horizontally, but also tilt to allow horizontal and vertical adjustment of the laser beam.

Note:
Angular optics are also required to perform flatness measurements.

Each flatness measurement kit contains:

• 2 flatness mirrors
• 1 50 mm flatness base
• 1 100 mm flatness base
• 1 150 mm flatness base

Part number: A-8003-0442  Flatness measurement kit

Specification

Where:
A = displayed flatness reading
M = length of diagonal in metres
F = length of diagonal in feet
