Chapter 10 Phase Contrast Types of Specimens for Phase Contrast Historical Background of Phase Contrast

Abstract

Phase contrast makes living, unstained microscopic structures visible. Normally the difference in refractive index between a living microscopic structure and its surrounding environment is so small that the structure refracts very little light. Light is, however, diffracted by the specimen. Diffracted light is, on average, slowed down by 1/4 of a wavelength… (More)
