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.
