Laser
interferometer LP 30 - Calibration of CMM and inspection of
machine tool geometry
Laser interferometer LN 10 - OEM high accuracy laser measurement
system
Calibration of length
measuring systems- etherodyne (2 frequencies) laser
interferometer
One of the world's most accurate and flexible laser calibration
systems, its wavelength accuracy ?.02 ppm, and physical separation between the laser
source (50°C) and the optical components
(interferometer/reflector) guarantee the highest
measurement accuracy, higher than any 3D tracker or tracer
system.
Typical application are
accuracy assessment of machine tools, CMMs, even references and
other linear positioning systems.
LP30 laser interferometer system can be used to determine linear
positioning and straightness errors in machine axes, to improve
performance through targeted maintenance and correction for
linear positioning errors using error compensation (using 5
sensors for measurement of air and material temperature, air
humidity and air pressure).
Extremely compact and light (13 kg including tripod), reliable
and cost-effective.
Sofware according following standard: PN - 93 M55580, ISO/DIS
230, PN - 93 M55580 , ISO 230-2 , NMTBA , VDI/DGQ 3441 and BSI BS
4656 Part 16.
LP30 has been used
for applications up to 100 m, although for such distances air and
temperature gradients should be taken into account.
A patented software technology allows measurement of straightness
with a single travel of the interferometer along
the axis, this is expecially useful when setting up in inspecting
machine tools.A full range of accessories allow inspection of all
geometric parameters.
A calibration certificate issued by the German Metrology Institute PTB in Braunschweig can be required. Feanor has been working with the German Metrology Institute on important FP4 SMT Research Projects in Length Measuring Systems and Length Abbe Measuring Machines.
