PI releases high-precision linear stage line

PI (Physik Instrumente) LP offers the PI Micos product line of precision linear stage positioners. More than 20 product types are available—from miniature translation stages and positioning ranges of 40mm to high-load, linear translation stages for long travel ranges, to 1 meter.

UPM160 Series ultra high precision linear stage.

The linear stage positioners can be used in semiconductor alignment, biotechnology and aerospace applications; for fiber-optic alignment and microscopy applications; and in optics research, among other applications.

The new line features a selection of:

• positioning ranges from 40mm to 1,000mm,
• a precision class from 0.2µm to 1nm resolution,
• servo, stepper and linear motors, and
• crossed roller or linear recirculating bearings.

The motorized precision positioners come in a large variety of standard and custom versions. The versions range from low-cost, open loop stages with stepper motors and leadscrew drives to high-speed and high-accuracy models with linear encoders featuring up to 1nm resolution. 

Most stages also come in vacuum-compatible and clean-room compatible versions. Customers can choose between rotary servo-motors, linear servo motors and stepper motors. Closed-loop models are offered with optical high-resolution position feedback. In addition to single-axis precision linear stages, the company designs and manufactures XY-positioning stages, precision Z-stages (elevation stages) and precision rotation stages.

PI is the U.S. operation of piezo and nanopositioning systems manufacturer Physik Instrumente GmbH, Karlsruhe, Germany, which became the majority owner of Micos GmbH in September 2011.
