Custom Coated Grids Information
The Graticules Ltd. Chalkley Point Array - Model NG52 was designed to quickly determine the relationship of components to each other using random sampling.
An example of an application would be for when a researcher might want to see whether or not a certain drug affects the volume proportion of the cell types in a given organ. With this reticle, the proportion of points lying over the image of one type of component is statistically proportional to the area occupied by that component. The 25 points of the array are placed over the field of view at random so that a comparison can be made between the number of points touching the one type of component, with the number touching the other type of component in each viewing. A series of observations will yield an increasingly accurate ratio of the comparative incidence of each type of particle.
