Surgical Supermicroscope MITAKA MM77

Mitaka’s most advanced optical platform ever made

Mitaka MM77 Supermicroscope

Built on an entirely new optical platform, the MM77 features a 30 mm aperture lens system, paired with Mitaka’s brand-new 10:1 advanced zoom system. This combination delivers Mitaka’s signature high resolution and magnification while preserving a broad field of view at low magnification and ensuring exceptional light transmission from the lens to the surgeon’s eyepiece.

Outstanding Resolution

The unique optical system of the Mitaka MM77, delivers 135 lp/mm native optical resolution, resulting in brilliant contrast, colour representation, and, ultimately, an incredible depiction of the smallest anatomical details.

A 10:1 surgical optical zoom

The wide-range zoom system allows 10-times magnification without changing the working distance. The same ratio applies to increasing the field of view, enabling an exceptionally wide view at full zoom-out.

Native magnification

Mitaka's 10:1 optical zoom reaches 21.6× native magnification without focal length extenders.

Working distance

The compact design and reference range of focal lengths give plenty of room to create a workspace in the surgical field. It provides a 200–650 mm variable working distance - comfortable and safe.

Feature of MM77

High-Speed Zoom

Despite being extended to 10:1 compared to previously available zoom ratios, the zoom operation has been developed to an ultra-fast level. Repeated numerous times during a single procedure, it provides smooth, immediate, and reliable performance, saving time and enabling smarter, faster work.

Feature of MM77

30mm diameter zoom aperture

The 30 mm zoom aperture carries more light through the optical path to the eyepiece and the camera. The enhanced brightness is a direct result of the large zoom aperture with a 30 mm diameter.

Smart and compact

Feature of SOH stand

Auto Balance

The latest generation of the Mitaka SOH stand delivers not only the overhead ergonomics pioneered by our engineers and one-hand repositioning with electromagnetic brakes on all axes but also features effortless and quick automatic balancing with the one push of a button, without requiring the microscope to be placed in specific positions.

Damping system

The SOH microscope stand features shock-absorbing technology developed through years of experience in designing and manufacturing observatory astronomical telescopes. This system dampens vibrations caused by external forces as well as those generated during manoeuvring.\

Drape suction unit

The suction system wraps the drape to the microscope, reducing size and interference in the operating field.

"Zero-weight" feeling

Seamless harmony between operator and technology

Full Auto Balance provides light manoeuvring and a stable feel. Precise repositioning is easily achievable even with one hand, allowing uninterrupted workflow in a comfortable, fatigue-free posture even during long surgeries.

Variable binocular adjustments

The rotating binocular mechanism for both the main surgeon and the assistant allows adjustment of height and position, accommodating differences in operator height for maximum comfort or specific procedural requirements.

Lateral tilt rotating binoculars

The lateral tilt allows for an angled trajectory of the microscope in challenging access areas while maintaining the microsurgeon’s ergonomic and comfortable posture, particularly without compromising the cervical spine.

Independent focus adjustment

The front assistant binocular is equipped with its own manual focus override for fine focus adjustment independent from the main surgeon’s focus. A useful feature to maintain focus throughout the procedure in case of misalignments.
