ZEISS OPMI PRO magis
ZEISS OPMI PRO magis is a surgical microscope intended for neurosurgery, otolaryngology (ENT), reconstructive and plastic surgery, and other fields of microsurgery. The model has a motorized 1:6 zoom and a motorized fine focus mechanism with an 18 mm range, which focuses the image by moving a fixed focal length objective. Coaxial fiber-optic illumination is supplied by a light source in the suspension system, while magnetic brakes allow the head to be locked in the selected position. Individual units may differ in their suspension system, binocular tube, eyepieces and equipment for control, co-observation and image recording, so the available functions should be considered in relation to each unit’s complete configuration.
What distinguishes the ZEISS OPMI PRO magis?
ZEISS OPMI PRO magis is a multidisciplinary surgical microscope that combines motorized magnification adjustment and fine focusing with head positioning. Its capabilities depend on the complete configuration, including the suspension system and equipment for observation, control and image recording. The designations S5, S8 and S81 refer to suspension systems, rather than variants of the microscope itself. Other models from the brand are presented on the ZEISS manufacturer page.
Applications of the ZEISS OPMI PRO magis
ZEISS OPMI PRO magis is intended for applications in neurosurgery, otolaryngology (ENT), plastic and reconstructive surgery and other fields of microsurgery that use multidisciplinary microscopes. The motorized zoom and fine focus mechanism adjust magnification and focus, while magnetic brakes assist with positioning the head. Observation, control and image recording capabilities depend on each unit’s complete configuration.
Optics, zoom and focusing
ZEISS OPMI PRO magis uses a motorized 1:6 zoom to change the image scale. A separate motorized fine focus mechanism with an 18 mm range focuses the image by moving the fixed focal length objective. The model can be equipped with different optical components, so total magnification and field of view depend on the configuration, while the nominal working distance depends on the objective used.
Positioning, brakes and control
The ZEISS OPMI PRO magis head can be rotated and tilted, and friction adjustment allows the resistance to movement to be set. Magnetic brakes released from the handgrips make it easier to reposition the head and hold it in the selected position. Smooth positioning requires the complete configuration, including the mounted equipment, to be correctly balanced.
The motorized zoom and fine focus mechanism are operated using controls at the head. Buttons in the adjustable handgrips release the magnetic brakes during positioning. Depending on the configuration, the system can be equipped with an optional foot control panel or hand control panel for operating the motorized functions.
Illumination, co-observation and image recording
ZEISS OPMI PRO magis uses coaxial illumination delivered to the head through a light guide. The 12 V/100 W halogen light source is located in the suspension system. The S8 stand can also be fitted with an additional Superlux 300 xenon light source. With an f = 200 mm objective, the illuminated field diameter can be adjusted from 55 to 11 mm to match the illuminated area to the field of observation.
ZEISS OPMI PRO magis equipment may include a stereo bridge for co-observation and accessories for image recording. These allow an assistant to view the image or enable it to be recorded, depending on the components used. They are not standard equipment for the model, so the capabilities of an individual unit should be determined from its actual configuration.
The PRO magis head and suspension system
PRO magis is a microscope head combined with a suitable suspension system to form a complete system. It can work with the S8 and S81 systems, as well as the S5 equipped with a compatible coupling. The choice of stand affects the installation method, positioning, light source and additional equipment. The full specification of an individual unit therefore comprises the head, the suspension system used and the remaining equipment.
ZEISS OPMI PRO magis technical specifications
The table below presents the main specifications of the ZEISS OPMI PRO magis head and features that depend on the equipment. It does not include specifications of the S5, S8 and S81 suspension systems. Total magnification and field of view do not have a single value common to all units, as they depend on the complete optical configuration.

What affects the price of a used ZEISS OPMI PRO magis?
On the second-hand market, the price of a used ZEISS OPMI PRO magis depends on the technical condition, completeness and equipment of the individual unit, including its suspension system, optical path, light source and accessories for co-observation or image recording. At Medical Elektro, we do not offer different levels of preparation: every unit is refurbished to the same standard. The price is determined individually for the complete configuration.
Refurbished ZEISS OPMI PRO magis microscopes at Medical Elektro
“Used” means that the microscope has been operated before. A refurbished surgical microscope is a used device that has undergone a multistage process of preparation for sale.
Refurbishment at Medical Elektro follows a single standard covering each unit’s complete configuration. For ZEISS OPMI PRO magis, this includes the microscope head, the appropriate suspension system and the actual equipment. Each refurbished unit has its own photographs and a description matching its configuration, and comes with a 12-month warranty. The full scope is described on the surgical microscope refurbishment process page.
