Variable Magnification Lenses

Variable magnification lenses can be used to provide adjustable image magnification capability to a range of imaging applications such as microscopy or factory automation. Variable magnification lenses are imaging components designed to be integrated with imaging systems to provide controllable image magnification capability. When working with variable magnification lenses, it is necessary to manually refocus the lens as magnification changes. This has the advantage of allowing an imaging system to be precisely optimised for each degree of magnification. A wide range of variable magnification lenses are available, suitable for many imaging needs in a variety of magnifications. A greater degree of control can be achieved using manual refocusing, which makes variable magnification ideal for many applications that do not require an automated magnification adjustment. These lenses are a good low-cost alternative to other automatically refocusing lenses and are available for integration into a variety of imaging or microscopy systems.
