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
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, 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.
Software 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.
