Product TOP
Laserscale for motion control to achieve high resolution and high speed.
It can be used not only as a scale for high-speed control of stages and picometer-level fine control, but also as a sensor for high-resolution tilt control of tilt tables.
- Maximum resolution : 6.1 pm Maximum response speed : 5 m/s
- Wide angle tolerance of ±30 min
- Equipped with a long-life laser diode
- Low noise
- Excellent interpolation accuracy in combination with BD700
- 1.5D and 2D scales are also available
