Finder / Locator Grid for SEM Specimens

Designed for use with large specimens, this grid can be used to locate and isolate areas of interest.

A central annulus surrounds the required area, with a small pointer for orientation.
The long arms are tapered to show the direction in which to move and are identified by N, S, E, W.
Two small markers of 500 m and 300 m lengths are incorporated in the central ring.

The inner ring is 2mm inside diameter and 4mm outside diameter.
It is 16mm across the legs.
Thickness is approx. 12 m.
