Description
Achieve sub-pixel measurement precision with our professional 8MP 25mm M12 machine vision lens. Purpose-built for large-format 2/3″ image sensors, this high-resolution fixed focal lens delivers exceptional optical clarity with an industry-leading TV distortion of less than 0.1%. Featuring a narrow 20° horizontal field of view and a robust 6G all-glass optical design, it captures sharp, non-deformed imagery over medium-to-long distances, making it the ultimate tool for robotic guidance, precise dimensional measuring, and advanced factory automation.
Key Product Highlights
- Virtually Zero Distortion (<0.1%): Features an ultra-low TV distortion profile, ensuring absolute geometric accuracy for scanning, measuring, and automated inspection without digital corrections.
- 8MP Ultra-HD Industrial Clarity: Engineered with a high-resolving 6-layer all-glass structure (6G), preserving razor-sharp matrix details and contrast across the entire 2/3″ sensor area.
- Medium Telephoto 25mm Narrow Vision: Provides a tight 20° horizontal viewing angle, isolating target objects and components from a distance to minimize peripheral visual interference.
- Macro Inspection Capable (0.2m M.O.D.): With a Minimum Object Distance of just 20cm, this FA lens enables close-range, high-magnification scanning for micro-components on moving lines.

Frequently Asked Questions
- Q: Why is “<0.1% TV Distortion” crucial for factory automation (FA)?
- A: In precise metrology and sorting, curved lines create major measurement errors. A TV distortion rating of less than 0.1% makes this a true low distortion lens, allowing vision software to measure object dimensions down to the micron level without optical warp.
- Q: Can this 25mm lens fit standard consumer action cameras?
- A: While it uses a standard M12x0.5 thread, this lens features a 25mm narrow-angle/telephoto view. Consumer action cameras usually use wider lenses (e.g., 2.8mm or 3.4mm), meaning this lens is strictly optimized for industrial lenses and targeted area tracking.
- Q: What are the main benefits of the 6G all-glass structure?
- A: Plastic elements degrade and shift focus under shifting factory temperatures. The 6G all-glass layout ensures incredible thermal stability, exceptional scratch resistance, and excellent light transmission for 8MP cameras.
- Q: Can this lens be used on smaller sensor formats like 1/1.8″ or 1/2″?
- A: Yes. When mounted on a smaller sensor, the image will undergo a crop factor, resulting in a slightly tighter field of view. However, it will yield exceptional edge sharpness because you are utilizing the highest-quality center portion of the lens optics.
- Q: Is the iris adjustable on this 8MP M12 lens?
- A: No, it features a fixed aperture of F2.8. A fixed iris is highly preferred for automated machine vision lenses because it guarantees a consistent depth of field and exposure parameters across thousands of automated production runs.
- Q: Does this lens come with an integrated infrared (IR) filter?
- A: The standard 6G configuration allows maximum light throughput. Depending on your project requirements (such as daytime color fidelity or monochromatic 850nm/940nm laser illumination), custom optical filters can be pre-fitted to the rear element.
