Fluorite Crystal Mineral Structure Model

This Fluorite (CaF₂) crystal lattice model kit comes with 154 atoms for only $59.95. The model shows the 8:4 coordination structure which in turn illustrates its unique 4 cleavage planes.

Fluorite is particularly useful in the production of high quality optics. Fluorite lenses transmit visible, infrared and ultraviolet light, with low dispersion. That and a low refractive results in sharper images with less chromatic aberration. This is particularly useful in microscopy.
