Central Stop 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 1.560.
Transmitted Central Stop Illumination
Definition/Function:
Central stop dispersion staining requires a dedicated objective with an opaque stop at
the back focal plane 10% greater in diameter than the image
of the closed down substage iris. 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.
