Oblique 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 1.545. 
              
              
                Transmitted Oblique Brightfield Illumination
                
Definition/Function:
                With oblique illumination one side of the particle shows the wavelenghts for which the
                particle has the higher refractive index and the other side
                shows the wavelengths for which the mounting medium has the higher refractive index. 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 wavelengths for which the particle has the higher refractive index
                color one side of the particle and the wavelengths for which
                the mouning medium has the higher refractive index colors the other side of the
                particle.
