The M-122 translation stage from PI (Physik Instrumente) LP features a travel range of 25 mm and dimensions of 60 × 86 × 20 mm. Its servomotor direct drive provides up to 20 mm/s, a dynamic response that is faster than that of stepper motor drives. The device incorporates a 0.1-μm-resolution optical linear encoder that provides high linearity and repeatability, as well as cross roller bearings capable of high load capacity and guiding accuracy. The recirculating ball screw creates less friction than conventional leadscrews, resulting in longer life and lower maintenance. The stages can be combined to form compact X-Y and X-Y-Z systems and can be driven with the C-862 Mercury servomotor controller/driver or the C-843 PC board.
