Laser Scales
BS65
Laserscale easily achieves measurement and control by ultra high resolution less than 1nm.
Sinusoidal wave of approx.138nm signal period is generated by a hologram scale with high diffraction efficiency and a high resolution detecting head based on grating interference method, strong against disturbance by air pressure or current, plus easy to install (BS series).
Features
