MicroE Systems

MicroE Systems is a leading manufacturer of miniature, high-performance optical encoders. The company’s background in ultra-accuracy encoders for the Data Storage industry translates today into encoders with class-leading resolution, accuracy and value. Named Mercury™ and Mercury II™, these encoders enable significant size, weight and cost reductions of motion stages and subsystems while increasing positioning resolution, accuracy, repeatability and speed. Encoder resolutions range from 5μm to 1.2nm, linear, and up to 268M CPR, rotary.
