Operation Microscope YZ20T9 is one kind of dual tube binocular operation microscope. The assistant scope shares the same vision field as the main microscope.
Main microscope: Magnification changes in five steps.
Assistant microscope: Magnification changes in three steps, through which the assistant scope may be locked at 90° to the right or left of the main microscope. It can also be locked at the circle of 360° to the main microscope if the oblique illumination device should be taken away.
Illumination: Cold light source, bright and even, equipped with retina protection device, red reflex, inferred and ultraviolet filters.
