Magnification of a lens or a mirror shows how magnified the image of an object is. ... ifv is the image distance and u is the object distance. So, It can be also defined as the ratio of the height of the image to the height of the object. Why is magnification vu? Where f is t...

Magnification can be varied according to the size of the specimen and the level of detail required. The magnification of a lens is shown by a multiplication sign followed by the amount the lens magnifies, eg ×10. Magnification of the microscope= magnification of eyepiece × magnification of obj...
A magnification optical system forms an enlarged image of an object. It includes a refractive optical system including a plurality of lens groups; and a mirror train including a curved mirror, arranged in this order from an object side, a first focus structure configured to move the respective ...
smaller. They are sometimes erect and in other cases are inverted. The size of the image and whether it is erect or inverted, real or virtual, depend on the distance of the object from the lens or mirror relative to the focal length and on the type of lens or mirror (plane, convex,...

Optical system featuring change in magnification by combined lens and mirror motion The optical system disclosed is incorporated in a copying machine and has provision for changing magnification of original documents of diverse sizes while maintaining a common image plane projection and enabling the use ...
In the basic configuration of a telescope, parallel incoming rays are converted into parallel rays at the output of the ocular lens (eyepiece), and only in the optical system of the observing eye they are focused to the retina, where one would ideally obtain one image point for each angular...
