Nikon interference phase contrast
Webb24 sep. 2024 · As mentioned in a much earlier post, the Nikon IPC was apparently intended to function solely with the old Nikon S-series (short barrel) Achromat objectives, even though much better Nikon optics were readily available, even back then! This odd design limitation seems to have killed the sales of the unit, at least in the US. WebbAt the image plane, the phase of the diffracted light would be out of phase with the direct light, but the amplitude of their interference would be almost the same as that of the direct light. This would result in very little specimen contrast.
