An optical magnification change system for provision of optical imaging of various size and microscope with such a

摘要

An optical magnification change in the system for providing of exactly two optical imaging size of the connection, wherein the magnification change in the system of three of an imaging beam path (b), which is penetrated one after the optical components (d1, d5, d4) comprises,a first subassembly (d1) of the three subassemblies (d1, d5, d4) with a fixed distance (k) of a second component group (d5) of the three subassemblies (d1, d5, d4) is arranged,a third subassembly (d4) of the three subassemblies (d1, d5, d4) between the first and the second component group (d1, d5) is arranged, andthe magnification change in the system has a positioning device (g) for the third subassembly (d4), which has exactly two predetermined operating states,wherein, in a first one of the two operating states of the third component (d4) with a predetermined first interval (k1) of the first component group (d1) is disposed and in a second of the two operating states the..
