Description
Upgrade your optical measurement and scanning systems with our premium 5MP 4.4mm M12 fixed focal lens. Meticulously engineered for 1/2.5″ format sensors, this high-performance wide angle lens breaks the limitations of standard optics by suppressing optical geometric distortion to <1%. Featuring a compact Φ14x19mm form factor and built-in IR filtration (IR Corrected Lens), it delivers mathematically precise, straight-line imaging. It is the ultimate choice for engineers requiring pixel-perfect accuracy in machine vision, industrial FA, and high-definition CCTV lens integrations.
Product Highlights
- Ultra-Low <1% Geometric Distortion: Eliminates the typical barrel bending of wide-angle optics, ensuring straight lines stay perfectly straight for high-accuracy barcode scanning and algorithmic measuring.
- 5MP Resolving Power with 1/2.5″ Format: Delivers crisp, high-contrast 5 Megapixel clarity across the entire frame, matching larger sensors perfectly without edge shading or resolution drop-off.
- Macro-Capable 0.1m Minimum Object Distance: Offers an exceptionally short 0.1-meter M.O.D., allowing close-up industrial inspections and tight-space component imaging without losing focus.
- Hybrid 4G2P+IRF Advanced Architecture: Utilizes 4 precision glass elements and 2 specialized plastic elements integrated with an IR-cut filter to ensure superior thermal stability and sharp day/night tracking.

Frequently Asked Questions
Q: What are the benefits of <1% distortion in machine vision applications?
A: Standard wide-angle lenses suffer from severe edge-stretching (barrel distortion). A distortion rate of less than 1% ensures that the spatial aspect ratio of objects remains perfectly accurate across the entire image plane, eliminating the need for complex, processor-heavy software distortion correction algorithms.
Q: What does the “4G2P+IRF” construction mean for image quality?
A: This indicates an optimized hybrid layout consisting of 4 Glass elements for high thermal stability and sharpness, 2 Plastic elements for precise aberration correction, and a built-in Infrared Filter (IRF). This combination guarantees excellent color reproduction while keeping the lens lightweight and cost-effective.
Q: Can this lens focus on objects that are very close to the camera?
A: Yes. This lens features an incredibly short Minimum Object Distance (M.O.D.) of just 0.1 meters (10cm). This makes it exceptional for macro-style close-up inspections, such as PCB trace analysis or small product defect auditing.
Q: Will this 1/2.5″ format lens cause vignetting on smaller sensors?
A: No, it will not cause vignetting. When a 1/2.5″ lens is used on smaller sensors like 1/2.8″ or 1/3″, it acts as a natural crop, utilizing the sharpest center portion of the lens. The only change will be a slightly narrower field of view (FOV) compared to the rated 80°.
Q: Is the iris adjustable if our environment has shifting light levels?
A: No, this is a Fixed Iris lens locked at F2.8. For applications with variable lighting, light compensation should be managed using your camera sensor’s automatic electronic shutter speed, gain control, or by adding dedicated LED strobe illumination.
Q: Does this lens support global environmental and export compliance standards?
A: Absolutely. Our manufacturing facilities operate under strict ISO9001 quality management guidelines. This lens fully complies with RoHS certifications, ensuring safe, hassle-free deployment in international markets including the US and EU.
