The MM90 surgical microscope is designed to deliver superior optical performance and intuitive surgical control. It features the industry’s only 8:1 optical zoom, allowing resolution to continuously increase across a broader magnification range. Surgeons benefit from exceptional one-handed maneuverability and hands-free mouth switch operation for precise positioning. Advanced imaging includes 4-chip 4K Deep-Diode ICG fluorescence with green overlay, Tri-fluoro visualization for ICG, fluorescein, and 5-ALA, plus integrated 4K recording and rapid replay. Its compact design, shortest ocular-corpus length, and 360-degree rotating side observer make it ideal for modern operating rooms worldwide.
