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 0.02 ppm, and physical
separation between the laser source (50°C) and the optical
components (interferometer/reflector) guarantee the
highest measurement accuracy, better 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 machines, 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.
Compensation avalìilable for main CNC manufacturers (Siemens,
Fanuc, NUM, Fagor, Heidenhain, others available at request).
LP30 has been used
for applications up to 100 m, although for such distances air and
temperature gradients should be taken into account. A special
version allows fast measurement in one direction up to 30 m/s.
A patented software technology allows 3D measurement of
straightness with a single travel of the
interferometer along the axis (without Wollaston prism), this is
expecially useful when setting up in inspecting machine tools. A
full range of accessories allows inspection of all geometric
parameters: straightness, linearity, angle, orthogonality,
flatness, vibrations.
Calibration certificate issued by the German Metrology Institute PTB in Braunschweig available. Feanor has been working with the German Metrology Institute on important FP4 SMT Research Projects in Length Measuring Systems and Length Abbe Measuring Machines.
