Transmitted Darkfield Dispersion Staining
                This is a collection of glass fiber that has a
                  refractive index of 1.550 in a high dispersion liquid with
                  a refractive index of 1.550.

Definition/Function:
                Transmitted darkfield makes any object in the field of view bright. That includes most
                opaque particles. If the refractive index of the particle and
                the mounting medium match at some visible wavelength but the dispersion curve of the
                mounting medium has a greater slope than that of the particle then
                the particle is color by all the wavelengths that are a certain distance from the
                matching wavelength.
