Abstract
An apparatus and method are disclosed for hard-docking of a tester head to a DUT, while permitting the angular alignment of a specimen to be inspected to the optical axis of an optical testing tool. In one example, a system for orthogonal alignment of a specimen to an optical axis of a collection optics is provided. The system comprises a self-leveling tabletop; a specimen holder coupled to the tabletop and held at a fix orientation; collection optics coupled to the tabletop; a plunger coupled to the tabletop and operable to maintain the leveling orientation of the tabletop; a control valve sensing the leveling orientation of the tabletop and coupled to the plunger to control the operation of the plunger; and an aligner coupled to the tabletop and operable to change the alignment of the optical axis of the collection optics with respect to the specimen without changing the fixed orientation of the specimen holder.
