Description
Upgrade your optical precision with our high-resolution 8MP 12mm M12 Low Distortion Lens. Engineered to support an expansive Max Φ11mm image format (optimized for 1/1.8″ sensors), this lens features a bright F2.0 aperture and a versatile manual focus design. With an ultra-short Minimum Object Distance (M.O.D.) of just 0.15m and an integrated IR Cut Filter (IRCF), it captures sharp, high-contrast imagery with less than -2% optical distortion, making it a reliable choice for advanced machine vision, industrial automation, and close-up inspection systems.
Key Highlights
- 8MP High-Definition Narrow Field: The 12mm focal length yields a concentrated 34° horizontal FOV, capturing distant details or micro-components with stunning 8-megapixel clarity.
- Ultra-Short 0.15m M.O.D.: Enables sharp, crisp focusing just 15cm away from the target, solving the blurry close-up rendering issues common in standard lenses.
- Large Φ11mm Image Format: Easily covers premium large-format 1/1.8″ sensors, preventing edge vignetting and ensuring bright, even illumination across the entire frame.
- Low Optical Distortion (< -2%): Delivers accurate linear geometry, reducing processing overhead for calibration algorithms in precision robotic vision.

Applications & Compatibility
Core Application Scenarios
This 8MP 12mm M12 lens is purpose-built for applications requiring exceptional close-range magnification or medium-distance tracking without edge deformation. It is highly optimized for Industrial Machine Vision inspection lines, such as barcode scanning, electronic component positioning, and PCB solder joint quality checks where the 0.15m short-focus capability is essential. Additionally, its narrow-angle design makes it ideal for Intelligent Transportation Systems (ITS) tracking lanes, facial recognition access terminals, and high-precision OCR reading devices. The robust manual focus ring guarantees stability under vibration-prone environments like robotic arm attachments or factory automation cells.

Frequently Asked Questions
- Q: What are the main benefits of a 12mm focal length on this M12 lens?
- A: A 12mm focal length provides a narrower, more focused field of view (34° horizontal on a 1/1.8″ sensor). This allows you to zoom in mechanically on specific targets from a distance or achieve higher pixel density on small components.
- Q: How does the manual focus feature benefit industrial setups?
- A: Manual focus gives you precise control over your exact working distance. Once locked into place on a factory line or inside an inspection machine, it ensures the focus remains completely fixed without drifting over time.
- Q: Can this lens handle a Max Φ11mm image circle without vignetting?
- A: Yes, the lens is specifically optical-engineered to support up to a Φ11mm image circle, meaning it perfectly matches large 1/1.8″ sensors with crisp resolution and no dark corners.
- Q: Does this lens require software-based distortion correction?
- A: With an optical distortion rating of less than -2%, this low distortion lens provides straight lines and true geometry right out of the box, saving valuable computing power on software correction.
- Q: What is the significance of the 0.15m Minimum Object Distance (M.O.D.)?
- A: It allows the camera to position itself as close as 15cm from the subject while maintaining sharp focus. This is a crucial advantage for desktop scanners, macro sorting bins, and compact medical inspection devices.
- Q: Is this M12 lens equipped with an IR Cut Filter?
- A: Yes, it features an integrated IR Cut Filter (IRCF) that filters out infrared light during daytime operations, preserving natural color accuracy and avoiding color distortion.
