A condenser (right) and its respective diaphragm (left) A condenser is an optical lens that renders a divergent light beam from a point light source into a parallel or converging beam to illuminate an object to be imaged. Condensers are an essential part of any imaging device, such as microscopes, enlargers, slide projectors, and telescopes.
Zemax is a software program used for designing and simulating optical systems. It is widely used in the field of optics and photonics for designing and analyzing the performance of lenses, cameras, telescopes, microscopes, and other optical systems.
The Nomarski prism causes the two rays to come to a focal point outside the body of the prism, and so allows greater flexibility when setting up the microscope, as the prism can be actively focused. 3. The two rays are focused by the condenser for passage through the sample. These two rays are focused so they will pass through two adjacent ...

Diagram illustrating the light path through a dark-field microscope. The steps are illustrated in the figure where an inverted microscope is used. Light enters the microscope for illumination of the sample. A specially sized disc, the patch stop (see figure), blocks some light from the light source, leaving an outer ring of illumination. A wide ...
For phase contrast microscopy the phase ring (at the back focal plane of the objective) and the annulus (at the back focal plane of the condenser lens) should appear in focus and in alignment. Bertrand lenses find use in creating interference figures and assisting in aligning a microscope to generate interference figures.
Liebig condenser. The Liebig condenser (/ ˈ l iː b ɪ ɡ /, LEE-big) [1] or straight condenser is a piece of laboratory equipment, specifically a condenser consisting of a straight glass tube surrounded by a water jacket. In typical laboratory operation, such as distillation, the condenser is clamped to a retort stand in vertical
A bright-field microscope has many important parts including; the condenser, the objective lens, the ocular lens, the diaphragm, and the aperture. Some other pieces of the microscope that are commonly known are the arm, the head, the illuminator, the base, the stage, the adjusters, and the brightness adjuster.
