Laser on granite surface For performance validation we have invested in several metrology tools, including AA grade granite plates, parallels, and squares, precision electronic indicators, and laser interferometers and optics.  Before shipment, every stage or motion assembly is tested to be sure it meets specifications.

Rotary Axis Calibrator Most linear stages are tested for yaw, pitch, straightness of travel, flatness of travel, linear accuracy and bidirectional repeatability. Standard tests for rotary stages include radial and axial error, wobble, rotation position accuracy, and position repeatability. With a sampling rate of up to 50KHz, Straightness Graph the laser interferometer is also capable of dynamic measurements such as velocity regulation and settling time.  Test results are included with the products.
