Leica M844 F40

Key Features and Benefits

• APO OptiChrome™ Technology: Delivers true-to-life color, enhanced contrast, and razor-sharp detail across the full depth of the surgical field.
  
• Brilliant Red Reflex: Patented QuadZoom™ optics and dual coaxial illumination enhance the red reflex for cataract and anterior segment procedures.
  
• Integrated InverterScope™: Allows seamless transitions between posterior and anterior segment views without equipment reconfiguration.
  
• Ergonomic Floor Stand (F40): Compact and motorized with electromagnetic brakes for smooth, effortless positioning.
  
• Xenon Illumination: Bright, natural light ensures deep and shadow-free cavity visibility with high color fidelity. Halogen bulbs are built into the head for additional flexibility.
  
• Stereo Coaxial Illumination (SCI): Maximizes depth perception and spatial orientation during retinal surgeries. This SCI technology is specific to the Carl Zeiss Lumera family; the Leica equivalent is the QuadZoom™ technology.
  
• Digital Imaging Options: Compatible with HD video systems for surgical recording, teaching, and consultation.
  
• Modular Configuration: Can be outfitted with accessories such as BIOM (Binocular Indirect Ophthalmo Microscope), assistant scopes, and 3D visualization tools.
