### Air Bearing Stage and Systems introduced by PI at Photonics West

Precision motion leader
PI (Physik Instrumente) has introduced their new air bearing stage and system capabilities at this year's Photonics West conference, to complement their comprehensive range of piezo nano positioning stages and hexapod micro positioning systems. With the 2014 acquisition of Nelson Air Bearing Products of New Hampshire, PI is building on over 200 man-years of in-house air bearing experience to offer linear, planar XY, and rotary air bearing stages to serve both the research and industrial markets. |

### XY Piezo Nanopositioners for Extreme Precision applications

Aerotech QNP-XY series piezo nanopositioning stages provide the resolution, linearity, repeatability, and high dynamics required for the most demanding applications from microscopy to optics alignment. With resolution to 0.15 nm, linearity to 0.007%, and repeatability to 2 nm, nanometer-level precision is assured. With the highest dynamics (resonant frequency and stiffness) of any other comparable stage in size and travel, users can achieve higher throughput in exacting processes. |

### Longer Travel Range for Micro Motorized Linear Stages

Zaber’s LSA Series of micro motorized linear stages is now available with a longer travel range – 25 mm, in addition to 10 mm. These stages are designed to fit into the most restrictive spaces without sacrificing performance or features. Small but powerful, these stages provide ultra-fine positioning with a microstep size of < 25 nm, < 1 um repeatability, up to 10 mm/s speed, and up to 3.5 kg thrust. |

### Low Cost, High Precision XY Alignment Stages

Optimal Engineering Systems’ (OES) low profile, XYθ (theta) stages are designed for high precision alignment applications. These stages move in an XY-plane and rotate around the center of the XY-plane. The terms alignment table, or XY-rotation stage are often used interchangeably with XYθ, or XY-theta stage. |

### Manual Positioning Stages

Manual positioning stages are the cost-effective solution when a simple yet precise motion control is needed.
Optimal Engineering Systems (OES) offers a complete range of manual positioning hardware, including: |

### Customizable Gantry Systems

Zaber’s G-LSQ Series gantry systems are complete, turn-key solutions that include the controller (A-MCB2 two-axis controller), power supply, and all the accessories needed for operation. G-LSQ gantries are based on the robust and versatile LSQ Series of linear stages, which offer various travel ranges from 150 to 450 mm per axis, and speeds up to 330 mm/s. |

### New Hexapod 6-Axis Positioners: Low Cost, High Speed & High Load Versions

Precision Motion specialist
PI (Physik Instrumente) introduces a new 6-axis positioning system with 1000lbs load capacity. The new H-850KMLD hexapod system provides 1µm minimum incremental motion over a 100mm travel range in XY and 0.5µm in the Z direction. The repeatability in the 3 linear axes is ±1µm, and ±5µrad / 9µrad in the rotary axes. |

### A-MCB2 Two-Axis Controller Offers 2D Linear and Circular Interpolation

Zaber’s A-MCB2 Series controller is now capable of controlling and driving two axes of bipolar stepper motors or actuators independently or in coordinated 2D linear and circular interpolation. Zaber’s A-MCB2 two-axis controller now includes built-in path generation algorithms that obey acceleration and velocity constraints, and enable 2D linear and circular interpolation. |

### High Force Air Bearing XY Voice Coil Positioning Stage

H2W introduces its latest custom XY voice coil positioning stage (VCS08-700-08/350-AB-01-MC-XY) which is guided by precision air bearings. This minimizes the amount of friction and reduces the pitch, yaw, and roll in the system. The stage is driven by three NCC series moving coil type linear actuators which are guided by parallel air bearing shafts. It is operated under closed loop position control. |

### Miniature XY Brushless Linear Motor Positioning Gantry

H2W Technologies offers a miniature XY brushless linear motor positioning gantry (SRS-002-007/003-003-01-XY), which is ideal for applications that require a low profile and more than 2 inches of stroke. The stages are driven by brushless linear motors which are guided by precision recirculating linear ball bearing blocks and rails. Each axis incorporates 1 micron resolution linear encoders for position feedback. |
