In an objective light
In optical engineering, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be a single lens or mirror, or combinations of several optical elements. They are used in microscopes, binoculars, telescopes, cameras, slide … See more The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being … See more In a telescope the objective is the lens at the front end of a refracting telescope (such as binoculars or telescopic sights) or the image-forming See more Camera lenses (usually referred to as "photographic objectives" instead of simply "objectives" ) need to cover a large focal plane so are made up of a number of optical lens … See more • List of telescope parts and construction • Etendue See more WebObjective rear aperture:A hole or opening where light enters the objective.
