STATESVILLE HAUNTED PRISON Â®. The Prisoners have rioted, the guards have fled, a darkness has seized control of this Maximum Security Prison and our Warden has opened the gates for visitors.
Substage: The area under the stage, called the substage, may contain a diaphragm, a. condenser, or both. Diaphragm: The diaphragm regulates the amount of light passing from the light source. through the specimen and through the lens system of the microscope.
Light diffracted by the specimen is presented as an inverted cone of half-angle (Î±), which represents the limits of light that can enter the objective. In order to increase the effective aperture and resolving power of the microscope, a condenser (Figure 1(b)) is added to generate a ray cone on the illumination side of the specimen. This enables the objective to gather light rays that are the result of larger diffraction angles, increasing the resolution of the microscope system. The sum of the aperture angles of the objective and the condenser is referred to as the working aperture.
