Carl Zeiss f=170 Binocular Microscope Head Beam Splitter 10x/22B

Carl Zeiss f=170 Binocular Microscope Head | Beam Splitter | 10x/22B

The Carl Zeiss f=170 is a premium optical bridge assembly engineered for high-fidelity shared visualization. Designed specifically for integration with Zeiss OPMI surgical microscopes and advanced laboratory imaging systems, this unit functions as a high-efficiency Beam Splitter. It divides the primary optical path, allowing a lead surgeon and an assistant—or two laboratory researchers—to view the same surgical field or specimen simultaneously with identical magnification and clarity.

Featuring a 170mm focal length and matched 10x/22B wide-field eyepieces, this head provides an expansive 22mm field of view, critical for maintaining spatial awareness during intricate microsurgical or dissection procedures.

Technical & Clinical Advantages

• Lossless Beam Splitting: The Zeiss internal prisms are coated to ensure minimal light loss when splitting the beam. This provides both observers with a bright, high-contrast image, which is essential when working under low-light surgical conditions or using high-magnification objectives.

• 10x/22B Wide-Field Optics: The "B" designation indicates suitability for spectacle wearers (high eyepoint). The 22mm field of view reduces the "tunnel vision" effect, allowing for better visualization of the periphery of the surgical site.

• Ergonomic Dual Viewing: The f=170 focal length provides a comfortable working distance for the assistant. The adjustable viewing angles allow the bridge to be positioned to accommodate different heights and postures, reducing neck strain during long procedures.

• Modular Accessory Port: The side-mounted optical port allows for the seamless integration of a C-Mount camera adapter or a third observation tube without disrupting the primary dual-binocular setup.

• Zeiss "Plug-and-Play" Compatibility: Designed to mount directly onto Zeiss OPMI arms and intermediate tubes, ensuring the optical axis remains perfectly centered and parfocal across all viewing ports.

Applications

• Microsurgery (ENT/Ophthalmology/Neuro): Essential for teaching hospitals and surgical centers where a resident or assistant must follow the lead surgeon's movements in real-time.

• Laboratory Research: Ideal for tandem dissections or multi-user specimen analysis where shared 3D visualization is required.

• Digital Documentation: Used as a bridge to split light between a binocular head and a high-definition surgical camera system for live-streaming or recording.

Condition & Quality Assurance

• Status: Used – Very Good Condition.

• Integrity: The internal prisms are clear of fungal growth, delamination, or heavy dust. All mechanical adjustment knobs (IPD and tilt) move smoothly with appropriate tension. Minor cosmetic surface wear is present from prior clinical use but does not affect optical performance.

• Maintenance Requirement: As a reusable optical component, the external housing and eyepieces should be cleaned and disinfected according to Zeiss aseptic protocols prior to use in a sterile field in 2026.

• Professional Standards: With over 25 years of experience in high-end optics, Primis Medical ensures all Zeiss hardware is inspected for optical alignment and mechanical stability.

Shipping & Handling

• Precision Packaging: Shipped in custom-fit, high-density foam to protect the internal prism alignment and prevent eyepiece vibration during transit.

• Fast Dispatch: Ships within 1 business day via tracked insured courier.
