Biological microscope ML31
Routine biological microscope with trinocular observation tube ML31

MSHOT ML31 biological microscope received positive feeback from medical and educational area, it offers superior optical performance with excellent cost-effciency. Plan achromatic objectives are flat and clear in view, bring microscope users high contrast and sharpness image. Wide field of view eyepiece is high efficiency for microscopy work. The illumination employs cold LED light has high bright and stable lighting. Rigid and durable construction makes the microscope maintains high performance even after long time using. More with 0.5X C-mount adapter for user to connect digital camera freely, mostly reproduce equal image in eyepiece.
