In comparison, bright field microscopy is the cheapest and simplest method to examine activated WebPhase contrast is preferable to bright field microscopy when high magnifications (400x, 1000x) are needed and the specimen is colorless or the details so fine that color does not show up well. In phase contrast a phase plate is placed in the light path. Barely refracted light passes through the center of the plate and is not retarded.
