The Zeiss OPMI 11/S21 surgical microscope, the essential ally for ENT surgeons
The Zeiss OPMI 11 surgical microscope, mounted on the S21 stand, is a benchmark device in ENT operating theatres. Designed to combine ergonomics, optical power and mechanical reliability, it is an indispensable tool for professionals seeking precision and visual comfort during delicate surgical procedures. Compact, easy to handle and stable, it can be used flexibly in all operating configurations.
This microscope stands out in particular for its German-quality optical system, featuring wide-field lenses, a large objective diameter and exceptional visual resolution. Thanks to its 10x wide-field eyepieces (or 12.5x optional) and magnification range from 4x to 25x in five steps, the OPMI 11 allows the surgeon to adjust the desired level of detail in real time while maintaining a panoramic view of the surgical field. This flexibility is enhanced by the precise adjustment of the interpupillary distance, ranging from 50 to 75 mm, and the customisable tilt of the binocular heads.
Lighting plays a central role in the performance of the microscope. The Zeiss OPMI 11 is equipped with a 12V/100W halogen light source, transmitted via fibre optics, which provides a field of illumination of up to 65 mm. An automatic mercury switch allows for quick and easy switching on, limiting handling during procedures. This system guarantees white, homogeneous light without shadows, which is essential for clear visualisation of fine and complex internal structures.
The S21 arm on which the microscope is mounted ensures flawless stability and smooth movement in all directions. Its robust metal design guarantees increased durability, even with intensive use. The integrated fine focus system allows for precise image adjustments without effort or vibration, enabling the user to concentrate fully on the surgical procedure. Thanks to its modular components, the microscope can be customised to suit a variety of surgical techniques and clinical specialities.
The versatile Zeiss OPMI 11/S21 can also accommodate multiple filters, including a standard UV filter or an optional green filter. It is compatible with a wide range of interchangeable objective lenses (from 150 to 400 mm), allowing the working distance to be adjusted according to the type of procedure. In addition, its robust metal components make it particularly suitable for demanding hospital environments.
The Zeiss OPMI 11/S21 is much more than just an operating microscope: it is a tool of excellence that meets the most stringent standards of microsurgery. Its ability to combine reliability, optical precision and ergonomics makes it a strategic choice for healthcare facilities seeking to provide their surgeons with an instrument that matches their skills and clinical requirements.
