SMZ-Series is a big zoom steromicroscope with high performance, the zoom ratio is1:6.5 . The series adopt building block structure and can easily and quickly mount the functional components, such as photographic system, CCD, Digital camera for the convenience of taking pictures and coaxial illuminating. It adopts the parallel optical paths. And the common objective with non-coaxial imaging techniques, which improve defintion of the visual field edge, strengthen three-dimension effect and offer a clear effect on observation object with bright background. The series microscopes have a character of big working table, comfortable used easy operating and reliable performance . It can be used extensively for medical and hygienic work, agriculture and electron and precision machinery. It is particularly suitable for the test of LC naked film, LCD printing paste, LED production, PCB board, pressing and Plating and electron components, Biology, jewelry.
