1. it provides an amazingly clear fine observations by using xenon light source
2. -2° +6° coxial illumination greatly improves the intension and range of red light reflex.
3. UV-proof and heat absorption reduces the harm to intraocular tissues and make the patient feel more comfortable

4. Schott optics ensure the surgeons a bright,balanced and fine observation
5. Apochromatic technology used in the optical design,ensures coaxial light focus and make a clearer field of view
6. lock device under the microscope arm prevents accident from happening
7. fine focusing knob is under the bottom of assistant binocular the obervation of the assistant's microscope can be finely focused independently from the main microscope to avoid the different observations from the su
