Carl Zeiss f=175 T* Microscope Optical Lens Component | Germany

The Carl Zeiss f=175 is a high-precision optical element engineered for advanced light management within professional microscopy systems. As a genuine German-manufactured component, it features the world-renowned Zeiss T (T-Star) multi-layer anti-reflective coating*. This specific coating technology is designed to maximize light transmission and significantly reduce internal reflections (ghosting), resulting in images with superior contrast, color fidelity, and edge-to-edge sharpness.

With a 175mm focal length, this lens typically functions as a tube lens or a relay lens within an infinity-corrected optical pathway. It is designed to converge parallel light beams from an objective lens to form a high-resolution intermediate image.

 Key Specifications

• Manufacturer: Carl Zeiss (Germany)

• Optical Coating: T* (T-Star) Multi-layer Anti-Reflective

• Mounting Interface: Precision Threaded Mount

• Product Type: Modular Optical Component (Tube/Relay Lens)

• Protection: Includes specialized protective storage case

Technical & Clinical Advantages

• Zeiss T Coating Technology:* By virtually eliminating stray light and reflections at the glass-to-air interfaces, the T* coating ensures that the maximum amount of light reaches the observer or camera sensor. This is critical for low-light applications such as fluorescence microscopy or deep-tissue surgical visualization.

• Precision 175mm Focal Length: The specification is a standard within many Zeiss modular systems. When used as a tube lens, it determines the total system magnification in conjunction with the objective lens focal length according to the formula:

• Achromatic Correction: Zeiss modular lenses are engineered to minimize chromatic and spherical aberrations, ensuring that light across the visible spectrum converges at the same focal point for a distortion-free image.

• Modular Integration: The threaded mount allows for seamless integration into customized optical "sandwiches," including beam splitters, laser ports, or auxiliary camera adapters.

Applications

• Surgical Microscopy (OPMI): Used as a corrective or relay element in surgical microscope heads to maintain parfocality across multiple viewing ports.

• Laboratory Research: Integration into custom-built light-sheet or confocal microscope rigs requiring high-transmission infinity optics.

• Industrial Inspection: High-resolution imaging of semiconductor wafers or precision mechanical components where contrast is paramount.

• Digital Imaging: Functioning as the primary tube lens for C-mount camera assemblies in specialized diagnostic setups.

Condition & Quality Assurance

• Status: Excellent Condition.

• Optical Integrity: The T* coating is intact with no visible scratches, delamination, or "cleaning marks." The glass is free of fungus and internal haze.

• Mechanical Quality: The mounting threads are clean and free of cross-threading, ensuring a secure, centered fit within your optical housing.

• Storage: The included protective case has shielded the lens from environmental dust and mechanical shock, preserving its factory-grade alignment for use in 2026.

Shipping & Handling

• Secure Logistics: Shipped in double-layered protective packaging with moisture-absorbent silica to ensure the lens arrives in a pristine, laboratory-ready state.

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