The ratio of the focal length of the objective and the eyepiece, when mounted in a standard tube length, gives an approximate magnification of the system. Due to their design, compound microscopes have improved resolving power and contrast in comparison to simple microscopes, [ 11 ] and can be used to view the structure, shape and motility of a ...
The microscope offers magnification up to 1000 times with two wide field eyepieces, along with three premium quality objective lenses and a 360-degree swiveling monocular head.
The actual power or magnification of a compound optical microscope is the product of the powers of the eyepiece and the objective lens. For example a 10x eyepiece magnification and a 100x objective lens magnification gives a total magnification of 1,000×.
One of the most important properties of microscope objectives is their magnification.The magnification typically ranges from 4× to 100×. It is combined with the magnification of the eyepiece to determine the overall magnification of the microscope; a 4× objective with a 10× eyepiece produces an image that is 40 times the size of the object.
The field of view seen through an eyepiece varies, depending on the magnification achieved when connected to a particular telescope or microscope, and also on properties of the eyepiece itself. Eyepieces are differentiated by their field stop , which is the narrowest aperture that light entering the eyepiece must pass through to reach the field ...
By convention, for magnifying glasses and optical microscopes, where the size of the object is a linear dimension and the apparent size is an angle, the magnification is the ratio between the apparent (angular) size as seen in the eyepiece and the angular size of the object when placed at the conventional closest distance of distinct vision: 25 ...
Area per high-power field for some microscope types: Olympus BX50, BX40 or BH2 or AO: 0.096 mm 2 [1] AO with 10x eyepiece: 0.12 mm 2 [1] Olympus with 10x eyepiece: 0.16 mm 2 [1] Nikon Eclipse E400 with 10x eyepiece and 40x objective: 0.25mm 2 [2] Leitz Ortholux: 0.27 mm 2 [1] Leitz Diaplan: 0.31 mm 2 [1]
The first optical instruments were telescopes used for magnification of distant images, and microscopes used for magnifying very tiny images. Since the days of Galileo and Van Leeuwenhoek, these instruments have been greatly improved and extended into other portions of the electromagnetic spectrum.
