Eyepiece Reticles from Graticules Ltd.

The Merz Reticle (36 Point) Model NGM1

Introduction:
Stereology is the science of gathering information about a three dimensional object from an only two dimensional section of that three dimensional structure.

These kinds of measurements are usually made with these stereology reticles in the following manner:

1. An adequate representation of sections of a specimen is obtained.
2. The reticle is superimposed upon the specimen (or micrograph/projected image of the section).
3. Finally the interaction between the superimposed reticle and the test sections are recorded.

The Merz Reticle (36 Point) for Stereology - Model NGM1
This unique reticle is used to estimate the three dimensional surface areas or the surface density of a component in a given volume, when the component does not have a random orientation. It comprises a test system with parallel curved lines used for measuring the intersection of points.
