WebA condenser is an optical device which is used for conditioning illumination light, for example in an optical microscope or an image projector. Typically, it contains one or more lenses and a diaphragm . Even multi-lens … A condenser is an optical lens which renders a divergent beam from a point source into a parallel or converging beam to illuminate an object. Condensers are an essential part of any imaging device, such as microscopes, enlargers, slide projectors, and telescopes. The concept is applicable to all kinds of radiation undergoing optical transformation, such as electrons in elect…
