A highly accurate rotary encoder for calibration realizing ±0.1 arcsec accuracy.
Perfect for calibration and mapping of rotary axis of stages and machine tools.
(Winner of the JSPE technology award 2018)

1D, 1.5D and 2D Laserscale high accuracy linear encoders for measurements and calibration.
The BL50H generate an analogue sin/cos signal with 400nm wavelength.
With the interpolator BD700 resolutions with very low noise level and very low interpolation errors up 6pm can be generated.
Therefore, the BL50H series fits perfectly for position feedback applications in X/Y stages.

The lever gauge of the DM series enables scanning measurements in various positions. This means that measurements are possible even in areas that are difficult to access or in cramped areas.
The digital display LU20 measurement values can be shown in different display views. The absolute measuring values can be transferred via Bluetooth.
