Phase contrast microscopy was first described by Dutch physicist Frits Zernike in 1934. The phase contrast technique has an optical mechanism that allows living cells to be examined in a natural state, no dye necessary. The change in phase is increased by a half a wavelength by the microscope's transparent phase-plate creating a difference in brightness. The dynamics of the biological processes can be seen with a sharp clarity in high contrast.
