Microscope illumination


Most modern microscopes have a  built-in illuminator,   which makes it much easier to ensure that you have an evenly-illuminated specimen. This Zeiss microscope also has a built in iris diaphragm   which ensures that the field of view of the diaphragm can be adjusted to correspond wit the field of view of the objective. Illumination intensity is controlled by the knob just in front of the diaphragm. The system is relatively simple to use.
