Description
Dispersion staining (DS) microscopy refers to a family of analytical optical staining methods used to help determine the identity of unknown microscopic materials. Nikon offers both center stop-type DS (C-DS) and phase-type DS (R-DS) objectives to better meet customer needs. C-DS center stop objectives feature a stop in the center of an aperture plane, blocking light that is not heavily refracted. R-DS phase contrast objectives for dispersion staining are similar, but the phase plate blocks the waveband where the refractive indices of the two materials are similar.
