YZ20T9 OPERATION MICROSCOPE ( OPHTHALMOLOGY)
· Characteristics
· Five-step magnifications for main microscope, three-step magnifications for assistant microscope; Fine focusing for assistant microscope keeps the same clearness as main microscope.
· Lens made of imported glass from Germany can reduce the optical aberration.
· X/Y movement can be automatically centered.
· Independent electrical box has automatical diagnosis function, which is very convenient for repair if necessary.
