YZ20T9 ophthalmic operating microscope

Advanced apochromatic technology and unique optical balanced technology effectively improves the binocular visual fusions, strengthenes in third dimension and reduces surgeon’s tireness during operations.

Fine focusing knob is under the bottom of assistant binocular. The observation of the
assistant’s microscope can be finely focused independently of the main microscope to
avoid different observation from surgeons.
20°oblique illumination can also be used as slit illumination. Slit width is continuously  adjustable.

For ophthalmic use
