ABSTRACT:
A micro-object is affixed to a mounting structure at a desired relative orientation. The micro-object may be a tool tip optimized to work with particular microscope objectives permitting the tip to be imaged along with the object surface and used to make measurements or modifications through a travel range along the microscope imaging axis equal to or nearly equal to the working distance of the given objective. The tool tip may have a lengths exceeding 80 microns, say up to several millimeters; even the longest tips can have widths of tens of microns.
