Phase contrast electron microscopy utilizing phase plates has been considered suitable for high-contrast observation of weak phase objects. This novel technique was newly applied to histochemically stained strong phase objects of osmificated biological specimens. Sections of various thicknesses, specifically stained for the Golgi apparatus by the ZIO technique using the heavy metals Zn and Os, were observed with a phase contrast electron microscope in Zernike and Hilbert imaging modes. Quantitative analysis of image contrast in real space and the power spectrum in Fourier space showed a high-contrast gain even for strong phase objects. This result clearly indicates that phase contrast electron microscopy can be effectively used not only for weak phase objects but also for strong phase objects in biology.
