Carl Zeiss f=170 Binocular Microscope Head w/ 10x/21B Eyepieces

Carl Zeiss f=170 Binocular Microscope Head | 10x/21B Eyepieces

The Carl Zeiss f=170 is a high-performance binocular observation module engineered for the OPMI surgical microscope series and advanced laboratory platforms. Featuring a 170mm focal length, this head is designed to provide a natural, undistorted view of the surgical or clinical field, delivering the exceptional contrast and edge-to-edge clarity that are the hallmarks of Zeiss optics.

Equipped with 10x/21B wide-field eyepieces, this unit offers a balanced magnification profile with a generous 21mm field of view. Its modular design ensures seamless integration into existing Zeiss-compatible stands and beam splitters, making it an ideal replacement or upgrade for high-stakes 2026 clinical environments.

Key Specifications

• Manufacturer: Carl Zeiss

• Focal Length: $f=170\text{ mm}$

• Eyepieces: 10x / 21B (Matched Pair)

• Optical Path: Parallel (Binocular)

• Mounting Interface: Standard Zeiss-compatible dovetail

• Adjustments: Interpupillary distance and dual independent diopter controls

• Housing: Professional-grade cast metal

Technical & Clinical Advantages

• Zeiss Optical Integrity: The internal prisms and lenses are multi-coated to maximize light transmission and eliminate ghosting. This is critical in low-light surgical scenarios (e.g., deep-cavity ENT or ophthalmic work) where every lumen counts.

• Wide-Field Visualization: The 21B eyepieces provide a 21mm field number, allowing the observer to maintain peripheral awareness of the surgical site, which reduces the need for constant repositioning of the microscope head.

• Customized Ergonomics: Independent diopter adjustments on both eyepieces compensate for the user's individual eyesight, reducing eye strain during lengthy 2026 surgical procedures. The smooth interpupillary adjustment ensures a perfectly fused binocular image.

• Modular Versatility: Designed with the standard Zeiss interface, this head can be swapped onto OPMI MD, OPMI CS, or OPMI 1 systems in seconds, providing a "plug-and-play" solution for equipment maintenance or specialized setups.

• Robust Metal Construction: Unlike plastic-housed alternatives, the Zeiss metal housing provides superior thermal stability, ensuring the optical alignment remains true despite the heat generated by high-intensity xenon or halogen illumination systems.

Condition & Quality Assurance

• Status: Used – Very Good Condition.

• Optical Health: No known chips, scratches, or delamination on the internal or external glass surfaces. The view is clear and bright.

• Mechanical Function: Interpupillary and diopter adjustments move smoothly with appropriate resistance.

• Cosmetic Note: Shows minor wear consistent with professional clinical use. Note: One eyepiece is missing the rubber eyecup; however, this is a non-optical component and does not impact the visual performance or mechanical function of the head.

• Maintenance: The unit has been thoroughly inspected to ensure it meets the rigorous standards required for high-magnification observation.

Applications

• Surgical Microscopy: Primary observation head for OPMI-series microscopes in ENT, Plastics, and Ophthalmology.

• Clinical Laboratories: High-end biological or metallurgical observation.

• Teaching & Documentation: Integration with beam splitters for assistant viewing or video capture.

Shipping & Handling

• Secure Logistics: Shipped in high-density, shock-absorbent packaging to protect the precision-aligned internal prisms.

• Fast Dispatch: Ships within 1 business day.
