===Condenser===
The [[condenser (microscope)|condenser]] is a lens designed to focus light from the illumination source onto the sample. The condenser may also include other features, such as a [[diaphragm (optics)|diaphragm]] and/or filters, to manage the quality and intensity of the illumination. For illumination techniques like [[dark field]], [[phase contrast]] and [[differential interference contrast]] microscopy additional optical components must be precisely aligned in the light path.{{cn|date=December 2024}}
