NZ20A Operation Microscope

Features


The primary microscope has five-step magnification change while the secondary microscope has three-step magnification change. The secondary microscope has independent optical adjusting device to ensure the definition consistent with the primary one.

Schott optic lenses is used to reduce the optical distortion of primary and secondary microscope  and improve the clarity and depth significantly.

Multi-layer coating technology is used on all the lenses to prevent mildew and reflection and enhance lens transmittance.

Two objective lenses is equipped to use in ophthalmology, neurosurgery, plastic surgery and microsurgery, etc.

The product has left and right, tilt tilting function. The tilting direction and angle can be controlled by manual or electric.

Zoom and focus can be manually or electrically controlled and the focus speed has 5 steps.

The independent electrical control box, with self fault diagnosis function, can make maintenance easy.
