Abstract

The stage plate of a sample carrying stage for optical instruments has a piezoelectric translator that drives the stage plate centrally and directly, and a linear guide comprising at least two elastic elements to guide the stage plate. The elastic elements are arranged coaxially to the piezoelectric translator, which extends through a central recess in the elastic elements.
