WebThe field lens can be integrated into the ocular. The second lens of the ocular may then be called the eye lens. Field Lens in an Illumination System In the illumination system of an overhead projector, for example, … WebAn aperture stop is the opening which limits the amount of light which passes through an optical system. For example, the adjustable diaphragm near the front of a compound camera lens is the aperture stop for the lens. The amount of light admitted is controlled by the diameter of the diaphragm opening which is indicated on the camera by the "f ...
