WebFigure 3. (a) The numerical aperture of a microscope objective lens refers to the light-gathering ability of the lens and is calculated using half the angle of acceptance . (b) Here, is half the acceptance angle for light rays from a specimen entering a camera lens, and is the diameter of the aperture that controls the light entering the lens. WebStereo microscopes (also called Dissecting microscope) are branched out from other light microscopes for the application of viewing “3D” objects. These include substantial specimens, such as insects, feathers, leaves, rocks, sand grains, gems, coins, and stamps, etc. Functionally, a stereo microscope is like a powerful magnifying glass. WebThe limitations on resolution (and therefore magnifying power) imposed by the constraints of a simple microscope can be overcome by the use of a compound microscope, in which the image is relayed by two lens arrays. One of them, the objective, has a short focal length and is placed close to the object being examined. It is used to form a real image in the … binge a thon
