Zeiss OPMI Neuro NC-4

Zeiss OPMI Neuro NC-4 Surgical Microscope

The Zeiss OPMI Neuro NC-4 is one of the most advanced and successful neurosurgical microscopes developed by Zeiss. Built with apochromatic coatings, AutoFocus technology, and a Heads-Up Display, this system ensures crystal-clear imaging, enhanced depth perception, and superior color fidelity. It integrates seamlessly with leading neuronavigation platforms such as BrainLAB, Medtronic, Radionics, and Visualization Technology.

The NC-4 microscope stand features a 300W Xenon light source with a halogen backup, motorized focal adjustment, and fully adjustable binoculars for enhanced surgical ergonomics. This microscope was the precursor to the Zeiss OPMI Pentero, offering similar capabilities at a more affordable price.
