Ophthalmic Operation Microscope YZ20T9

Advanced apochromatic technology and unique optical balanced technology effectively improve the binocular visual fusions, strengthened the third dimension, and reduce the surgeon’s tiredness.
The fine focusing knob is under the bottom of the assistant binocular. The observation of the assistant’s microscope can be finely focused independently of the main microscope to avoid different observations from surgeons.
20°oblique illumination can also be used as slit illumination. The slit width is continuously adjustable.
For ophthalmic use.
