The product is a double binocular operation microscope designed

for two men.It has excellent optical performance and it is comfortable to be used.

◆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.
