New High Precision Dual-axis ZVR-60-60 Series of Lift and Pitch Stages have been released by Optimal Engineering Systems, Inc. (OES). These compact stages feature 60 mm +/- 2 mm (2.362 in. +/- 0.078 in.) of vertical travel and a vertically mounted rotary stage. The scissor lift design combined with precision roller bearings and slide rails assures smooth motion and very high parallelism throughout the raising and lowering of the table. The Rotary Stage is capable of continuous 360 degrees CW or CCW rotation. The ZVR-60-60-01 Lift and Pitch Stage (shown) is driven by Two-Phase Stepper Motors with micro-stepping capabilities. The vertical repeatability is typically +/- 5 microns and typical positional accuracy is 15 microns. The ZVR-60-60-04 is driven with Two-Phase Stepper Motors and has Quadrature Incremental Optical Encoders for position verification.

The ZVR-60-60-02 is driven by Three-Phase Brushless Servo Motors with Quadrature Incremental Optical Encoders, and the ZVR60-60-03 is driven by DC Brushed Servo Motors with Quadrature Incremental Optical Encoders.  The Servo Motor options provide higher repeatability and positional accuracy typical of a closed loop system, and faster travel speeds.

The integration of a high parallelism vertical lift and a vertically mounted high precision rotary stage is ideal for: Laser pointing, laser milling and drilling, camera mount, mirror alignment, range finding, sighting, assembly and inspection, scanning, and reverse engineering, in laboratory and manufacturing applications.

These stages require a motion controller that can be ordered as a complete plug-and-play system with RS-232, USB, joystick, trackball, and keypad control.
