The system which increases or decrease phase changes of undiffracted and diffracted light is called
|
|
Condenser annulus
|
|
|
Objective lens
|
|
|
Phase plate
|
|
|
None of the above

Explanation:
Detailed explanation-1: -A phase plate is mounted in or near the objective rear focal plane (see Figures 4 and 5) in order to selectively alter the phase and amplitude of the surround (or undeviated) light passing through the specimen.
Detailed explanation-2: -A reliable light source should be used in phase-contrast microscopy for forming the enlarged image of biological samples. Natural sunlight can also be used in the process. However, another artificial light source can also be used.
