XL-80 laser produces an extremely stable laser beam, with a
wavelength that is traceable back to national and international
Laser frequency stability ±0.05 ppm over 1 year and
±0.02 ppm over 1 hour is achieved by dynamic thermal control of
the laser tube length to within a few nanometres.
Linear measurement accuracy ±0.5 ppm over the whole
environmental range ie, from 0 ºC - 40 ºC (32 ºF - 104 ºF) and
650 mbar - 1150 mbar. Readings can be taken at up to 50 kHz,
with a maximum linear measurement speed of 4 m/s and a linear
resolution of 1 nm; even at maximum speed.
Integrated USB means there is no requirement for a
separate laser-to-PC interface.
LED status lights indicate
the laser status and signal strength, providing a convenient
alternative to the software's on-screen indicators.
standard (40 m) and long (80 m) range modes.
Analogue I/O port allows
for analogue signal output and a trigger signal input.
Warm-up time is less than 6 minutes.
External, switch mode power supply ensures
90 V - 264 V flexibility in input voltage.
All of the above features make the XL-80 quick and easy to use.

XC-80 compensator is a crucial factor in your XL system's
linear measurement accuracy. Featuring intelligent sensors that
process the readings at source, the compensator very accurately
measures air temperature, air pressure and relative humidity.
Changes in these conditions can affect the wavelength of the laser
light and the measurement readings taken.
The XC-80 uses the sensor readings to modify the nominal value of
the laser wavelength to give a true value, which is then used in
calculations to virtually eliminate any measurement errors resulting
from these variations.
If you are interested in accuracy you NEED effective wavelength
Key features of XC-80 include:
Uniform compensation - The design of the XC-80 and
sensors ensures uniform and extremely accurate readings over the
full range of environmental operating conditions.
Frequent sensor updates - This can be done
automatically every seven seconds, as indicated by LED status
lights on the XC-80 unit.
Integrated USB -
The integral USB connection means there is no separate PC
interface and no separate power supply (the USB supplies the
XC-80 and sensors' power).
Lightweight - The
XC-80 weighs 550 g, and together with the XL-80, weighs just
over 3 kg (including connecting cables, XL power supply and
Intelligent air and material temperature sensors - The
integral microprocessors analyse and process the sensor's output
before sending digital temperature values to the XC-80
compensator. This offers more secure measurements and is a key
reason why the XC-80 is so compact and also ensures sensors are
fully interchangeable without comprimising accuracy.
Up to three material temperature sensors can also be
attached to the XC-80 compensator to allow linear measurements
to be normalised to a standard material temperature of 20 °C.
Versatile sensor cables - The standard 5 m long sensor
cables are detachable for easy replacement and can be screwed
together for extended lengths on longer machines.
compensation is NOT required for angular or straightness
measurements when using a Renishaw system as these are calculated
from differences in two beam paths close together, where the
environmental factors self cancel. As rotary axis, flatness and
squareness measurements are also based on these measurements they
also do not require environmental compensation.
Unless you are using a dedicated measurement rig, then you are
likely to need a mounting stage (and in most cases a tripod) to
adjust the laser's position relative to the desired measurement
XL mounting stage allows for precise angular rotation and
translation of the XL-80. It is designed to be left attached to
the laser unit for easy storage and quick set-up.
A "quick fit/release" mechanism enables rapid and secure fixing
to a tripod. For those applications where tripod mounting is
not convenient, e.g. for mounting directly on a machine tool
table, the stage and laser can also be mounted on to most
standard magnetic bases, using an optional adapter with M8
The new Universal tripod has been extensively tested to provide
a stable, adjustable base in a compact, lightweight unit.
