M820 F40 Surgical Microscope: Optimized Precision and Performance for Medical Interventions

The Leica M820 F40 surgical microscope embodies excellence in optical precision, ergonomic comfort, and functional versatility. Designed to meet the needs of surgeons during delicate interventions, this microscope combines exclusive optical innovations with reliable mechanics and an extensive range of integrated features. Equipped with Leica's QuadZoom™ and OptiChrome™ technologies, the M820 F40 delivers images of exceptional quality, offering clarity, contrast, and image definition that assist in real-time decision-making and enable detailed visualization of anatomical structures.

The QuadZoom™ optical system is a core element of this microscope, featuring optics with four beam paths. This innovation provides full stereopsis for both the surgeon and assistant, a crucial advantage in procedures where real-time collaboration is essential. Thanks to Leica’s patented OptiChrome™ optics, the M820 F40 produces images with true-to-life colors and high detail precision, which is critical in ocular and neurosurgeries where every millimeter matters. The microscope also includes a motorized zoom changer with a 6:1 zoom range, allowing smooth transitions from an overview to a detailed view without interrupting the procedure flow.

In addition to its optical performance, the M820 F40 is designed to provide maximum comfort for the surgeon, a vital factor for lengthy procedures. Leica’s ErgonOptic™ system allows ergonomic adjustments, such as wide-field eyepieces specially designed for eyeglass wearers and an adjustable binocular tube from 10° to 50°. Users can also adjust the inclination to their preferences, with a motorized tilt range of +15° to -50°. These features enable prolonged, fatigue-free visualization, even in demanding working positions.

The M820 F40 also offers flexibility through various working distances. It is compatible with objectives offering distances of 175 mm, 200 mm, and 225 mm, making it adaptable to a range of surgical applications. The motorized X/Y coupling with a 50 mm x 50 mm travel range allows effortless precision movement, and the motorized focusing control (54 mm with automatic reset) ensures constant image sharpness throughout the intervention.

Another standout feature of the M820 F40 is its integrated OttoFlex™ II illumination system, designed to provide an intense, uniform red reflex while minimizing stray light. This functionality is crucial for ophthalmic surgeries, where the red reflex enhances visualization of internal eye structures. With a quick-change halogen lamp mount, the lighting system ensures a consistent light flow without interruptions. Primary illumination is provided by a 12 V/50 W halogen lamp, and the field diameter can be adjusted from 4 mm to 35 mm at a 200 mm working distance, allowing optimal adaptation for different procedures.

The M820 F40 also excels in documentation integration, with a wide range of accessories for video recording and photography. Leica 2D and D2D systems allow real-time video recording, ideal for training or documenting surgical procedures. Video adapters, such as C-Mount video adapters, photo tubes, and dual mounts, enable simultaneous use of a video camera and an SLR camera. This is particularly beneficial for teams aiming to capture high-resolution footage for case reviews or conferences.

Mounted on the F40 floor stand, the M820 F40 offers great stability and flexible maneuverability, thanks to its castors and electromagnetic brakes. The stand can support a maximum load of 12.2 kg, allowing various accessories to be attached without compromising stability. The arm extends up to 1492 mm and is gas-spring balanced for optimal precision. The stand includes three rotation axes, allowing smooth movement in all required directions.

The Leica M820 F40 is a cutting-edge surgical microscope designed to meet the needs of the most complex interventions. With its advanced optics, ergonomic features, integrated lighting system, and comprehensive documentation options, it is the ideal choice for surgical teams demanding maximum performance and reliability.
