Renishaw, is adding to its extensive optical encoder range with the launch of the Vionic series, a new set of ultra-high accuracy, super-compact all-in-one digital incremental encoders. Designed for ...

Optical encoders have been used to measure position, speed, acceleration and motion direction for decades, but now they are finding new applications where high performance and miniaturization are ...

Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

It takes considerable time and effort to manufacture “perfect” surfaces. The mirrors on NASA’s James Webb Space Telescope, with a surface area of about 25 m 2 and finished to accuracies of 25 nm, took ...
