Description
Maximize your vision system’s precision with our high-resolution 5MP 4.0mm M12 low distortion lens, engineered explicitly for 1/3″ image format sensors. Integrating a highly efficient 2G2P (2 Glass + 2 Plastic) hybrid optical structure and a bright F2.8 aperture, this fixed focal lens delivers crisp data capture and color fidelity across a versatile 64° horizontal field of view. Boasting an ultra-low geometric distortion of less than -0.2%, it stands as an elite choice for developers and system integrators seeking high-precision machine vision and clear surveillance solutions.
Key Product Highlights
- Near-Zero Distortion (< -0.2%): Eliminates image warping to ensure accurate measurement calculations without complex software calibration.
- Ultra-High 5MP Resolution: Resolves extreme detail and fine textures across the entire 1/3″ target surface.
- Fast F2.8 Aperture Performance: Draws in ample light to produce vivid imaging under low or variable ambient lighting.
- Optimal 64° Horizontal F.O.V.: Supplies a balanced mid-wide viewing angle that covers expansive areas without fisheye curvature.
- Standard M12 Board Compatibility: Designed with a precise M12x0.5 threaded mount for direct, tool-free installation onto mainstream board cameras.

Target Applications & Compatible Devices
Core Application Scenarios
The 5MP 4.0mm M12 low distortion lens is highly optimized for integration into factory automation (FA lens) assemblies, automated retail environments, and smart infrastructure networks. Its unmatched linearity with an optical distortion under -0.2% makes it crucial for industrial barcode readers, printed circuit board (PCB) optical inspection rigs, and automated license plate recognition (ALPR) setups. Operating at a minimum object distance of just 10cm, this machine vision lens ensures sharp focus and clear boundaries, which is ideal for facial recognition access control gates and logistics package scanning tunnels where text tracking and structural measurement data must remain flawless.

Frequently Asked Questions
Q: Why should I choose a lens with less than -0.2% distortion for machine vision?
A: Lenses with distortion under -0.2% ensure that straight physical edges remain perfectly straight on the image sensor. This layout enables your AI or inspection algorithms to measure lengths and recognize text accurately without losing processing speed to software flattening.
Q: Can this 5MP M12 lens be used on a 1/2.8″ or 1/2.7″ sensor?
A: While it is built for a 1/3″ image format, a 1/2.8″ sensor is closely sized and might function well depending on the sensor’s exact active window area. However, testing is highly recommended to check for slight corner shading.
Q: What is the benefit of the 2G2P hybrid lens design?
A: The 2 Glass elements provide excellent center sharpness and high thermal stability to counter environmental heat, while the 2 Plastic elements keep the structure lightweight and cost-effective for mass deployment.
Q: Does this lens include a built-in Infrared (IR) cut filter?
A: This standard version is configured for visible light applications. If your project requires night-vision capabilities or custom near-infrared (NIR) passbands, we can customize the internal filter layout for you.
Q: How close can an object get to the lens while still maintaining a sharp focus?
A: The Minimum Object Distance (M.O.D.) is 0.1 meters (10 cm). This makes it highly efficient for scanning systems that handle close-up objects, like desktop document scanners or lab analyzer modules.
Q: Is the iris adjustable if lighting conditions change drastically?
A: No, this model features a fixed F2.8 iris. It performs beautifully in controlled factory lighting or environments using automated electronic shutter adjustments on the sensor side.
