The precision AR59-AV Motorized, 30 mm Clear Aperture Vertical Rotation Stage from Optimal Engineering Systems, Inc. (OES) features a 180:1 precision worm drive and deep grove ball bearings for a high resolution of ± 0.001^O  when microstepping (10 micro steps-per-step).  The parallelism of the table is less than 50µm.  The AR59-AV vertical rotation stage is ideal for:  Micro robotics, metrology, vision systems, positioning of mirrors and lasers, laser machining or scribing, electronic assembly, testing, and photonics. 

The clear aperture of the AR59-AV vertical rotation stage allows for vacuum and / or electrical lines, as well as optics.  A knob on the motor shaft allows for manual positioning.  This knob may be replaced with an optical encoder for position verification. This compact black anodized vertical rotation stage with a full 360^O of rotation and 30 mm (1.181 inches) clear aperture measures just 116.5 mm (4.587 inches) long x 80 mm (3.150 inches) high and the base is 60 mm (2.362 inches) x 60 mm (2.362 inches) for stability with 4 countersunk mounting holes for easy integration into new and existing applications. The 59 mm (1.181 inches) dia. table has 8 drilled and tapped (8-M3x6l) mounting holes for easy mounting of tooling, supports loads to 1 Kg 2.2 lb), and has scale to clearly display the angle of rotation.  Compatible with OES's line of motion controllers, the

AR59-AV vertical rotation stage is available as a Plug-and-Play system or with an optical encoder for position verification.  A larger vertical rotation stage and standard horizontal rotary stages are also available.
