KeevoDrive® Space 19mm – Type 3
The KeevoDrive® Space 19mm – type 3 micro focusing system is based on an eccentric with eccentricity of 1250 µm and travel range of up to 2500 µm.
The positioning unit is suitable for use in high-vacuum environments and is equipped with a stepper motor with 20 steps per rotation, thereby making it possible to operate the system in a simple, open loop control.
At the heart of the micro system is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1.
Benefits
1) Vacuum suitable lubrication
2) Robust control without feedback system
3) Zero backlash at optimised fit between speed and resolution
4) Step with in the range of nm
5) Integrated lens holder
