Optimal Engineering Systems, Inc. (OES) has added four goniometers to their expanding catalog of high precision positioning stages. The new, AK160-30 Goniometer Series feature precision ground worm gears with a 400:1 ratio and pre-loaded cross roller guides offer +/- 30 degrees of travel with 30 kg of load.

This series of goniometer stages feature four motor options.  The -01 option (pictured) is Stepper Motor driven. The -02 option is Three Phase-Servo Motor driven with a Quadrature Optical Encoder, the -03 version is DC Servomotor Driven with a Quadrature Optical Encoder, and the -04 option is Stepper Motor Driven with Quadrature Optical Encoders for position verification.  The highest resolutions, accuracy, and travel speeds are achieved with the servo motor options -02 and -03.

This AK160-30 Goniometer Series of Stages has a large 160 mm x 160 mm table with a precision pattern of mounting holes.  The center of rotation is 136 mm above the surface of the table and the radius of rotation is 203 mm making them ideal for: Microscopy, crystallography, measurement of surgical cutting blades, laser positioning, light measurement, and inspection applications.

The large footprint of these stages, 160 mm x 384 mm (without the motor), and a load capacity of 30 kg allows for stacking of a second AK160-30 goniometer stage or can be used as a building block in a multi-axes stage.  A calibrated indicator displays the angle of rotation.  The stage can be ordered with a fully plug-and-play compatible controller from OES.
