Real-life applications • Taiwan’s UMA Technolgy Inc develops optical testing equipment to ensure smartphone camera lens quality • UMA selected RGH 22 encoders with RGS-20 tape for a screwdriven X-Y mobile platform for lens positioning to improve the accuracy and precision of an existing motion stage The mobile platform is one of the core components of the testing equipment. Prior to redesign, the linear stage was driven by only stepper motors, offering an unsatisfactory level of repeatability. Installation of Renishaw’s RGH 22 encoder system has enhanced resolution to 0. 1µm, which improves our product competiveness “ “

RG 2 basic principles • Readhead sensor uses patented filtering optics OR • RS 422 digital output or 1 Vpp direct from readhead • Manual reference mark phasing. REE interpolator and REF interface use advanced algorithms to allow easy calibration • For higher performance applications, the REF interface and REE interpolator allow access to higher resolutions and reduced SDE
