The Environmental Light Microscope

This is one example of an environmental light microscope. It is configure to enable transmitted brightfield, darkfield, crossed linear polarized light, crossed circular polarized light, off-crossed polarized light, oblique illumination, and reflected darkfield illumination of any field of view within seconds. The abilty to characterize a particle in a few seconds with all of these different types of illumination without moving the particle is critical for an environmental sample.
