8.4 Phase-contrast units
Fundamentally there are two different ways for you to conduct the phase-contrast
procedure. A simple method and a more comprehensive method.
1. Simple phase-contrast unit
This consists of a simple PH condenser, a PH objective with a specific
magnification (10x, 20x, 40x or 100x), a PH slider, which is adapted to the lens
being used, a centring telescope and two green filters.
To use this, you need to replace the standard condenser of the microscope with
the PH condenser. One of the objectives in the nosepiece is also replaced with
the PH objective and this is positioned in the beam path.
