Nanometric Linear Actuator
The MPS Nanometric Linear Actuator is a high-force positioning system engineered for applications requiring sub-micron precision. It utilizes a stepper motor paired with a lead screw and a flexure-based mechanism to achieve fine incremental motion without the friction or wear associated with traditional bearings.
Core features:
Travel range | +/- 100 μm |
Maximum velocity, unloaded | 1.4 mm/s |
Drive force | 500 N |
Unidirectional repeatability (open loop) | 1 μm |
Minimum incremental motion | 0.05 μm |
Dimensions | 75 (L) x 55 (W) x 32 (H) mm |
| Motor type | Stepper |
| Motor regulation | Open loop |
| Drive mechanism | Lead screw |
| Homing reference | Optical barrier |
MPS Microsystems' technology is based on modular actuation platforms for precise lens positioning along different axes: axial (Z-axis), lateral (X and/or Y-axis), rotational (tip-tilt), or a combination of these. Each customer-specific solution is a scaled adaptation of our core technological platform, significantly reducing development time and costs.
To meet our clients' requirements, the following components can be customized:
• Selection of motor according to frequency, speed and acceleration requirements
• Ball screw or cam design and choice of ball bearings according to the required stroke
• Type of encoder and controller to match the required resolution
• Dimensional adaptations for a perfect match with the optical design.
• Adapters for precise positioning of fixed lenses.
• Bellows for high cleanliness
