The Leica OH4 surgical microscope provides superior reach, height, and clearance. The Leica OH4 floorstand moves easily and when the brakes are released, the microscope stabilizes in only 1.5 seconds and remains vibration free. By integrating new glass, glass coatings, and design parameters, Leica Microsystems’ high-resolution APO?OptiChrome™ technology delivers an expanded working distance, greater depth of focus, and brighter, yet safer illumination. The Leica FL800 integrated vascular fluorescence system allows the surgeon to see blood flow in vessels during surgery through the microscope.
