Laser Scales
BS78
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
High-speed and high-resolution, while maintaining stable, ultraprecision measuring. Ideal for precision stages, semiconductor inspection/manufacturing systems, and ultraprecision processing machines.
High-resolution scale with signal wavelength of approx138nm, outperforming light wave interferometer systems
High stability, unaffected by humidity, air pressure and air disturbances
Reference point accuracy : ±0.1μm
Scale accuracy : ±0.04μm or better (measuring length : 40 mm)
Completely non-contact design Return error is virtually eliminated.
Special non-magnetic and vacuum-compatible models available
Using low expansion glass : -0.7 x 10-6/ ℃ (measuring length : 10 to 420 mm)
