Description
Optimize your vision system with this high-precision 3MP 8mm M12 low distortion lens. Engineered for a 1/3″ image format, it delivers excellent narrow-to-medium field viewing with a 36° horizontal FOV. Featuring a fast F2.0 aperture and a robust 6G (6-glass) optical construction, this lens guarantees high-resolution image clarity and minimal chromatic aberration. With optical distortion strictly controlled under -6%, it stands out as a premier M12 fixed focal lens for applications requiring precise dimensional accuracy and clear long-distance targeting.
Key Product Highlights
- 3MP Crystal-Clear Resolution: Delivers sharp 3-Megapixel imaging, making it perfect for capturing fine text, barcodes, and analytical data.
- Low Optical Distortion (<-6%): Minimizes barrel distortion to ensure straight lines and accurate geometric proportions across the entire frame.
- 8mm Narrow-Angle Telephoto View: Provides a focused 45° diagonal field of view, ideal for long-range surveillance and tight-angle industrial inspections.
- High-Performance 6G Glass: Built with 6 premium glass elements that offer superior light transmission and exceptional thermal stability under harsh environments.
- Compact M12 Mount Design: Uses a standard M12x0.5 interface with a total track length (T.T.L.) of just 23.29mm, allowing seamless integration into ultra-compact hardware.

Applications & Compatible Devices
Core Application Scenes
This 3MP 8mm low distortion lens is specifically optimized for medium-to-long distance identification and high-accuracy inspection. It serves as an excellent component for industrial machine vision lens applications, such as automatic number plate recognition (ANPR/LPR) systems, toll station tracking, and facial recognition access gates. Thanks to its low distortion (<-6%), it is highly valued in logistics and warehousing for automated barcode or QR code scanning on rapid conveyor belts. It is also well-suited for facial-recognition-based smart retail checkouts and multi-lens panoramic stiching arrays where image deformation must be minimized.

Frequently Asked Questions
- Q: Why is a low distortion of <-6% important for this M12 lens?
- A: Most standard wide-angle or medium M12 lenses suffer from heavy barrel distortion. Controlling distortion under -6% prevents images from bending, which is critical for accurate measurements, barcode scanning, and facial recognition algorithms.
- Q: Can this 8mm lens be integrated into outdoor security cameras?
- A: Yes. The 6G (6-glass) construction ensures the lens will not suffer from focus drift or degradation due to temperature fluctuations, making it highly reliable for outdoor ITS and surveillance systems.
- Q: Does this lens include a built-in IR filter?
- A: This depends on your request. We offer both a standard optical glass version (dual-pass for day and night with external IR-cut switcher) and an integrated 650nm/850nm IR-cut filter version.
- Q: What is the benefit of the short 23.29mm T.T.L.?
- A: The short Total Track Length allows the lens to maintain an extremely compact profile, making it easy to install inside slim enclosures like smart door locks, sleek hand-held scanners, or miniature industrial sensors.
- Q: Can I request samples for testing before placing a bulk order?
- A: Absolutely. We provide sample units for engineering validation and testing. Please contact our sales team to arrange shipment and technical support.
