Angle calibration system Newly Released by Magnescale Interpolator unit BD350 Self-calibrating Rotary Encoder System SET-HD100 High angular accuracy ±0.1 arcsec achieved by unique Self-calibration function (Resolution: 0.0012 arcsec) Traceability of accuracy Qualified to the national primary standard by AIST (National Inst. of Advanced Industrial Science & Technology) High repeatability High repeatability in repeated measurements and for rotational direction Easy installation 15 minutes only from installation to measurement Compact and easy to carry

Self-compensating algorithm for angle accuracy Intelligent encoder can compensate its own errors. Magnescale original selfcalibration algorithm “VEDAmethod” *1 enables higher order correction with less heads, achieving up to 30th order compensation with only 6 heads at world-class high accuracy. High resolution and stability by Laserscale Laserscale allows high stability against environmental change such as pressure and temperature with the combination of high resolution, diffraction grating and a sensor head with symmetric optical path. Signal wavelength 1.24 arcsec = 6.0 μrad (250 nm on the...

High repeatability on the measurement machine e.g. Eccentric response Error [arcsec] (0 – Peak) Fine mechanical adjustment in the head unit keeps angle error from eccentricity at installation of a scale significantly low. High accuracy in repeating measurement and in CW/CCW direction enables high repeatability Non-contact design eliminates the effect from the encoder onto rotating axis of the measured target. Eccentricity [μm] (Peak - Peak) Easy installation 15 minutes from installation to measurement Remark: act. time depends on mounting conditions at customer site Example of installation onto...

Portable measurement kit Carry-on case is included to a standard package, which makes transportation easy and secures performance as an angular calibration system. Head unit BH300 Interpolator unit BD350 Recognition on outstanding technology Magnescale won “2018 JSPE technology award” by Japan Society for Precision Engineering for introduction of the rotary system with original, self-compensation algorism. Several research papers to explain the principle and development of the algorism were also published in journals of JSPE as well as Advanced Mechanical Design, Systems and Manufacturing. (1)...
