OPTIMAL ENGINEERING SYSTEMS' GONIOMETERS

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 10kg 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 Servo Motor options and Quadrature Optical Encoders. The AK120-45 Series of goniometer stages feature four motor options. The -01 option is Stepper Motor driven. The -02 option (pictured) is driven by a Three-Phase Brushless Servo Motor with a Quadrature Optical Encoder, the -03 version is DC Brushed Servo Motor Driven with a Quadrature Optical Encoder, and the -04 option is Stepper Motor Driven with the knob replaced with a Quadrature Optical Encoder for position verification. The highest resolutions, accuracy, and travel speeds are achieved with the servo motor options -02 and -03. This AK120-45 Goniometer Series of Stages has a large 104mm long by 90mm wide table with a precision pattern of mounting holes for precise location of fixtures. The height of rotation is 40.5mm above the surface of the table and the radius of rotation is 67mm making them ideal for: Microscopy, crystallography, measurement of surgical cutting blades, laser positioning, light measurement, and inspection applications.  The 10kg load capacity of these stages allows for stacking of a second goniometer stage or it can be used as a building block in a multi-axes stage including linear and rotary axis-stages. A calibrated indicator displays the angle of rotation. The stage can be ordered with a fully plug-and-play compatible motion controller from OES.
