Abstract
Abstract The present invention is a repositionable substrate for microscope applications, having a geometric pattern on its top surface to convey coordinate information. In a preferred embodiment, this geometric pattern is a plurality of geometric shapes having a common axis of symmetry. In a most preferred embodiment, these geometric shapes are concentric, with varying linewidth.
