An instrument for concentrating electricity by the effect of induction between conducting plates separated by a nonconducting plate.
A lens or mirror, usually of short focal distance, used to concentrate light upon an object.
provides an even cone of light that illuminates the specimen. Light from the condenser converges on the specimen, passes through it, and diverges to from an inverted illumination cone that is captured by the objective lens. The Abbe condenser is the most common. The condenser numerical aperture (NA) should be equal to or greater than the highest objective NA., usually 1.25 to 1.32 for a 100x oil objective. The resolving power of the optical system composed of condenser, objective ocular lens is limited to the lowest NA of its individual components.
A lens or mirror used in an optical system to collect the light being radiated from a source, which is then directed onto the gate of the projection system.
A simple lens system which concentrates light from a source into a beam. Condensers are used in equipment such as slide projectors,spotlights and enlargers. (see Focusing Spot)
The lens system mounted under the stage of the microscope to furnish a cone of light to the specimen. There are two basic types of condensers: brightfield and darkfield.
Generally a simple lens used to collect light and concentrate it on a particular area, as in enlarger or projector. Frequently in the form of two planoconvex lenses in a metal housing. A condenser, normally of the fresnel type, is used to ensure even illumination of the viewing screens on SLR cameras.
Optical system of one or more, often aspherical, convex lenses or mirror surfaces between the light source and the object which should be displayed. The condenser directs the light, which interfuses the object, into the object.
lens used to concentrate light on an object
a magick wand, mirror, or other device the magician crafts to "condense", or concentrate, these fluids
an optical element that gathers and concentrates light in a specific location.
collects all available light rays for direction up to the stage opening
condensador] the glass lens used to focus the light beam onto the objective lens, passing through the specimen.
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.
a combination of 2 or more lenses in slide or movie projectors designed to produce parallel rays of light illuminating the slide or film.
optical system which concentrates light rays from a wide source into a narrow beam. Condensers are used in spotlights and enlargers.
