Precision positioning specialist PI (Physik Instrumente) has released what it describes as a more affordable version of the M-663 piezo motor positioning stage for new applications where speed, repeatability and compact dimensions are critical, but nanometre resolution is not required.
PI says the M-663 miniature positioner is based on a unique design concept. The size of a matchbox, it integrates a high-speed ceramic linear motor, a precision guiding system and an optical linear encoder.
Previously only available with a 100nm type encoder, the new additional model targets applications with micron level precision. This is sufficient for many applications in bio-technology, medical design and for the adjustment and assembly of small mechanical components.
