PI V-551 Direct-Drive Linear Stages
PI V-551 Direct-Drive Linear Stages
PI V-551 combines an ironless linear motor with crossed-roller guidance and linear position feedback. The product description lists incremental encoder resolution of 0.2 nm, absolute encoder resolution of 2 nm and minimum incremental platform motion of 0.5 nm under the relevant conditions.
Review Summary
Consider PI V-551 Direct-Drive Linear Stages for optical inspection, metrology, photonics and semiconductor test equipment. Establish the required operating point and installation interfaces before choosing the configuration, and use a representative loaded cycle as the acceptance basis. Resolution is not overall accuracy. Load and environment influence the useful result.
