A condenser is an important component of compound microscopes. Objective lens magnification and eyepiece lens magnification are multiplied to give the total multiplication power of a compound microscope. The condenser, just below the stage, controls the amount of light and the contrast.
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 electron microscopy ...
Condensor: The main function of condenser lens is focussing the light on the specimen under observation. When very high powers of 400X are used, condenser lenses are very important. Presence of condenser lens gives a sharper image as compared to the microscope with no condenser lens. Base: Provides basal support for the microscope.
It is located above the condenser and below the stage. Most high quality microscopes include an Abbe condenser with an iris diaphragm. Combined, they control both the focus and quantity of light applied to the specimen. Condenser Focus Knob moves the condenser up or down to control the lighting focus on the specimen.
Understanding the Compound Microscope Parts and its Functions. Compound microscope is a widely used instrument in the field of life sciences helps solve many mysteries of life. The following article will cover information on its parts and functions. ... Condenser: The condenser is present at the base of the stage. It is usually connected to the ...
The substage condenser gathers light from the microscope light source and concentrates it into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield. It is critical that the condenser light cone be properly adjusted to optimize the intensity and angle of light entering the objective front lens.
Microscope Terms. This is a glossary of commonly used microscopy terms. See also our brief History of the Microscope. Abbe Condenser: A lens that is specially designed to mount under the stage and which typically moves in a vertical direction. An adjustable iris controls the diameter of the beam of light entering the lens system.
The function of the condenser. The condenser fulfills two functions in the microscope. It provides an area of evenly-illuminated light in the field of view at the specimen plane and illuminates the aperture of the objective uniformly with light of sufficient yet controllable angle.
Condenser Aperture Diaphragm Function. On upright microscopes, the condenser is located beneath the stage and serves to gather wavefronts from the microscope light source and concentrate them into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield. Inverted (tissue culture style) microscopes mount the ...
Microscopes with a stage condenser lens render a sharper image than those with no lens (at 400x). If your microscope has a maximum power of 400x, you will get the maximum benefit by using a condenser lenses rated at 0.65 NA or greater. 0.65 NA condenser lenses may be mounted in the stage and work quite well.
