Abstract

A wafer sample retainer for an electron microscope includes a clamp arranged to engage one or more wafer samples against a post. The clamp may be spring biased and may be operable by depressing a portion of a spring biased member to pivot the spring biased member away from a support post to create an opening to receive the samples. The sample holder may be removably mounted on a base which may be positioned using a conventional electron microscope positioner.
