Phase Contrast Condenser Lenses
A specific condenser with a ring printed on it, used for phase contrast. The
magnification of the objective must match the magnification of the condenser.
Condensers are used to concentrate the light from a transmitted light on a sample for
illumination and viewing.
Phase Contrast Condenser Assembly
For phase contrast kits without a turret, the condenser assembly is the
mount for the condenser lenses.
Phase Contrast Objective
A specific objective with a ring printed on it that is used for phase
contrast.
The objective is the bottom lens that determines the resolution of
the image in the microscope, and is one of the two lenses that
compound to make total magnification.
Phase Contrast Turret
The phase contrast condensers are mounted on a rotating
turret much like the objectives on a microscope are. The
turret also has brightfield and darkfield condensers.
