Target Applications & Device Compatibility
Core Application Scenarios
This 6mm fixed focal M12 lens is specifically designed for high-accuracy environments where image deformation cannot be tolerated. It excels in factory automation (FA), automated optical inspection (AOI), and industrial machine vision setups, such as PCB alignment and barcode scanning. Additionally, its compact Φ14mm profile makes it ideal for smart city traffic monitoring (ITS), smart parking access control, commercial biometric facial recognition terminals, and compact medical imaging devices where precise spatial measurements are mandatory.
Compatible Device List
- Sensors: Fully compatible with mainstream 1/3″ and 1/4″ CMOS/CCD sensors (e.g., Sony, Onsemi, OmniVision).
- Industrial Cameras: Fits compact USB/GigE board cameras, Raspberry Pi HQ camera modules, and Arduino vision kits.
- Security Hardware: Seamlessly replaces stock lenses in mainstream dome, bullet, and intercom camera modules.
- Customization: Supports tailored adjustments for focal lengths, F.O.V., and IR-cut filters to match specific OEM/ODM project demands.

Frequently Asked Questions
Q: What does “M12” mount mean for this lens?
A: An M12 mount indicates that the lens uses a metric 12mm thread diameter with a 0.5mm pitch. It is a standard interface often called a “board lens” or “S-mount,” widely used in mini cameras, CCTV modules, and industrial board cameras.
Q: Why is low distortion (< -0.1%) important?
A: Optical distortion warps the edges of an image. A distortion rate of less than 0.1% means the image is virtually flat and geometrically accurate. This is crucial for machine vision, AI recognition, and industrial measurements where precise data positioning is required.
Q: Can I use this 1/3″ format lens on a 1/2.8″ sensor?
A: Using this lens on a sensor larger than 1/3″ (such as 1/2.8″ or 1/2.7″) may cause vignetting, resulting in dark or blurry corners. For optimal 3MP performance, it is highly recommended to use it with 1/3″ or smaller sensors.
Q: What is the advantage of the 2G2P lens structure?
A: The 2G2P composition uses 2 Glass elements and 2 Plastic elements. The glass elements ensure high thermal stability, scratch resistance, and excellent light transmission, while the plastic elements allow for precision aspherical shaping to minimize distortion while keeping the lens lightweight and cost-effective.
Q: Does this lens support night vision or IR illumination?
A: This lens features a fixed iris and standard optical coatings. If your application requires day/night switching, it must be paired with an external camera-board IR-cut switcher (IRC filter) and 850nm/940nm IR LEDs to achieve clear night vision.
Q: What is the closest distance this lens can focus on?
A: The Minimum Object Distance (M.O.D.) is 0.1 meters (10 cm). This allows the camera to capture highly detailed, clear, and sharp images of objects placed very close to the lens surface, making it ideal for desktop scanners and macro industrial inspections.
