OpenFlexure Block Stage: 3D printed sub-micron mechanical precision
OpenFlexure Block Stage is a 3D printed flexure translation stage with sub-micron mechanical positioning. You can get the files to build it on GitHub. The project is 3-axis, short travel, high accuracy spinoff from the stage of the amazing OpenFlexure Microscope which we still haven’t covered, but we thought this stage deserved a post of its […]
