VAN NUYS, Calif. - Optimal Engineering Systems Inc. (OES) in Van Nuys, Calif., is introducing four high-resolution low-profile goniometers for microscopy, crystallography, measurement of surgical cutting blades, laser positioning, light measurement, and inspection applications.
The AK120-45 goniometer series features precision ground worm gears with a 296:1 ratio and pre-loaded cross roller guides, and plus-or-minus 45 degrees of travel with 10 kilograms of load.
The high resolution of 0.0006 degrees comes 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 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 104-millimeter long by 90-millimeter wide table with a precision pattern of mounting holes for precise location of fixtures. The height of rotation is 40.5 millimeters above the surface of the table and the radius of rotation is 67 millimeters.
The 10 kilograms 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.
