Optimal Engineering Systems, Inc. (OES) has added four high-resolution, low-profile goniometers to their expanding catalog of high precision positioning stages. This newly released, AK120-45 Goniometer Series features precision ground worm gears with a 296:1 ratio and pre-loaded cross roller guides, and +/- 45 degrees of travel with 10 kg of load. The very high resolution of 0.0006 degrees (2.16 Arcsec.) is realized when using the standard Two-Phase Stepper Motor driven by a 10 micro-steps per step micro-stepping driver or with the servomotor options and Quadrature Optical Encoders.

OES (Optimal Engineering Systems, Inc.) has added vertical stages to their extensive line of high accuracy, high resolution lift stages.  The Z110 Series of Z-axis Stages are available in travel strokes of 15 mm (0.590 in.), 30 mm (1.181 in.), 50 mm (1.969 in.), and 75 mm (2.953 in). These black anodized aluminum alloy stages feature preloaded crossed roller bearings and 1 mm per motor turn lead screws. 

Zero-Max has added to their field-proven ServoClass Flexible Shaft Coupling line with the introduction of the new ServoClass-HSN Coupling to address noise and vibration issues that can be experienced in certain high gain, high speed stepper/servomotor applications.
