MF31 LED Fluorescence Microscope


MF31 fluorescence microscope brings you a vivid full-range view and very high contrast fluorescence imaging by adopting excellent quality infinity optical system combined with blue LED fluorescence illuminators. Meanwhile, it will increase the samples' visibility and contrast in the bright field with Abbe condenser. With excellent imaging performance and east to operate, MF31 having been widely applied in the area of Medical diagnostic, teaching & researching, and biological research etc.
