Description
Achieve exceptional optical precision and extended depth of field with our flagship 12MP 50mm M12 Low Distortion Lens. Specifically engineered with an ultra-high-resolution 12 Megapixel optical design, this telephoto lens supports large-format sensors up to Max Φ11.3mm (fully covering 2/3″ sensors). Featuring a specialized fixed F8.0 small aperture, it yields an extraordinary depth of field (DOF) under intense industrial lighting or laser profiling. With a distortion rating of < 0.3% and a flexible Minimum Object Distance (M.O.D.) of 0.3m, this compact fixed focal lens delivers flawless edge-to-edge sharpness for high-end machine vision, factory automation (FA), and intelligent transportation systems (ITS).
Key Highlights
- 12MP Sub-Micron Resolution: Designed to fully resolve high-density 12-megapixel sensors, capturing micro-defects and complex structures without contrast loss.
- F8.0 Small Aperture & Deep DOF: The fixed F8.0 micro-aperture drastically increases depth of field, keeping multi-level or uneven components in focus simultaneously under strong illumination.
- Large 2/3″ Sensor Coverage: Supports a Max Φ11.3mm image circle, ensuring complete, vignette-free brightness across popular 2/3-inch and 1/2-inch industrial sensors.
- Ultra-Low Geometric Distortion (< 0.3%): Delivers nearly perfect linear mapping across the entire frame, saving computing overhead by eliminating the need for software calibration algorithms.

Applications & Compatibility
Core Application Scenarios
This 12MP 50mm F8.0 M12 lens is purpose-built for specialized industrial inspection corridors where intense external light grids require a telephoto compression and massive depth of field. It excels on Factory Automation (FA) and Machine Vision assembly lines for semiconductor wafer profiling, connector pin alignment, and uneven multi-level PCB inspection where components vary in height but must remain perfectly focused. The ultra-narrow 10.1° horizontal field of view allows the camera to be positioned at a safe working distance, making it ideal for Intelligent Transportation Systems (ITS) demanding precise long-range lane tracking and Automatic Number Plate Recognition (ANPR). Furthermore, its rugged fixed mechanism withstands heavy vibration in automated robotic picking arms and industrial desktop metrology scanners.

Frequently Asked Questions
- Q: Why does this 12MP lens use an F8.0 small aperture instead of a wider one?
- A: The F8.0 aperture is highly specialized for industrial environments with high-intensity external lighting (like ring lights or lasers). It vastly expands the Depth of Field (DOF), ensuring that objects at varying heights remain completely sharp without mechanical autofocusing.
- Q: Will this 50mm lens cause vignetting or dark corners on a 2/3″ sensor?
- A: No. The lens is optically engineered to cover a large Max Φ11.3mm image circle. It fully covers 2/3″, 1/1.8″, and 1/2″ sensors with excellent edge-to-edge brightness and no vignetting.
- Q: Does this telephoto lens require digital software-based distortion correction?
- A: No, with a geometric distortion rating below 0.3%, it delivers an almost perfectly linear image right out of the box, saving valuable onboard processor power during precise positioning or metrology tasks.
- Q: Can this 50mm telephoto lens focus closely on small components?
- A: Yes, despite its long 50mm focal length, it features a Minimum Object Distance (M.O.D.) of just 0.3 meters (30cm). This allows it to act as a macro-telephoto lens for close-up component tracking in cramped machinery housings.
- Q: Is there an integrated filter built into this model?
- A: This model uses high-transparency, multi-coated glass elements without a default filter to maximize optical resolution and pass visible/NIR wavelengths. Custom IR Cut Filters or bandpass filters can be integrated upon request.
- Q: Can the iris or focus be adjusted dynamically during operation?
- A: The iris is fixed at F8.0 to guarantee reliable, stable light throughput. The focus is manually set during initial installation and can be mechanically locked, eliminating moving parts and focus drift caused by robotic vibrations.
