The Graticules Ltd. Dust Analysis Sizing Reticle (Thompson Style) - Model G23 was designed for dust analyses and for the counting of particles in any of three areas of known size. The reticle is calibrated in the same manner as a normal eye piece reticle. The result is then used to calculate the area of any square. 

The pattern is produced as a glass "sandwich".
