Palm-Top-Sized Precision Translation Stage with Ballscrew Drive & Optical Linear Encoder

PI (Physik Instrumente) L.P. - a leading manufacturer of nanopositioning and precision motion-control equipment for bio-nanotechnology, photonics and semiconductor applications — introduces the M-122 palm-top-sized precision translation stage which combines compact dimensions, high dynamics & speed and very high accuracy at a competitive price.

Features & Advantages:

• Long Travel Range: 25 mm (1 inch)
• Very Compact: Smallest Ballscrew Stage w/ Linear Encoder: 60x86x20mm
• High Dynamics & Speed: Servo Motor Direct Drive provides up to 20 mm/sec, Significantly Better Dynamic Response than Stepper Motor Drives
• Precise: 0.1 µm Resolution Optical Linear Encoder for Higher Linearity & Repeatability
• Cross-Roller Bearings for High Load Capacity & Excellent Guiding Accuracy
• Long Life & Low Maintenance: Recirculating Ball Screw has much lower Friction than Conventional Leadscrews.

Typical Applications:

Metrology, Quality Assurance Testing, Micromachining, Photonics packaging, Fiber Positioning,

Smallest Ballscrew-Driven Stage with Linear Encoder

The M-122 features a space-saving, folded drive train with the servo motor and drive screw side-by-side. Equipped with a non-contacting optical linear encoder and a preloaded, precision-ground, ball-screw, these stages can provide much higher accuracy, better repeatability and dynamic performance than conventional stepper motor stages or rotary encoder-equipped servo motor stages.

Cost Effective Controllers

M-122 stages can be driven with the low-cost, networkable, C-862 Mercury™ servo motor controller/driver. For multiaxis applications, the C-843 PC Board is available.

Compact XY and XYZ Combinations

M-122 stages can be combined to form very compact XY and XYZ systems.

Low Friction, High Speed, Maintenance-Free

Due to its low-friction, the backlash-free ball screw yields significantly higher mechanical efficiency than leadscrews, and allows maintenance-free, high duty-cycle operation at high velocities -- up to 20 mm/sec.
