Laser interferometer LSP 30 (with cables) - Calibration of CMM and inspection of machine tool geometry
Laser interferometer LN 10 - OEM high accuracy laser measurement system
Wireless
HPI-3D fast laser interferometer (7 m/s) for ISO 230 inspection of machine tools


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 avalýilable 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. We ofer compensation for almost all CNC brands: Siemens, Fanuc, Heidenhain, Fagor, Fidia, and we can also adapt your special CNC model.
