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
High accuracy LASERSCALE with built-in optical zero point
Signal wavelength of 138nm
High accuracy, high resolution laser scale :Accuracy : L < 460 : (0.1+0.4L / 100) μm p-p(L=measuring length in mm)
Resolution :0.07nm
High accuracy optical reference point :± 0.1 μm
Measuring length :160 mm to 960 mm / 6.29" to 37.79
Easy installation
Little affected by disturbed air and changing atmospheric pressure.
