Combining 5MP HD with Near-Zero Distortion: An In-Depth Look at the JSD3428
In the hardware selection process for machine vision, facial recognition, barcode scanning, and modern video conferencing systems, engineers often face a tough trade-off: they need a wide enough field of view (FOV), but they cannot tolerate the edge stretching and curved lines that come with standard wide-angle lenses.
We introduce a perfect solution that breaks this deadlock—the JSD3428 5-Megapixel Ultra-Low Distortion Lens. While delivering a generous 96° field of view, it keeps optical distortion under an astonishing <-1%, truly achieving a "what you see is what you get" imaging experience.
Core Specifications at a Glance
Review the official technical indicators below to see the hardware capabilities of the JSD3428:

Field of View (FOV) | 96°(D) / 80°(H) / 65°(V) | A sweet-spot wide angle that offers a broad view while maintaining excellent center resolution. |
Image Format (Sensor Size) | 1/2.5" | Compatible with mainstream large-format sensors; ample light intake and superior low-light performance. |
Optical Structure (Element) | 2G2P (2 Glass + 2 Plastic) | An innovative hybrid design that balances high optical performance with exceptional cost-efficiency. |
Focal Length / Aperture | EFL 3.6mm / F2.8 | A classic focal length with excellent depth of field for clear, stable imaging. |
Mount & Dimensions | M12*0.5P / TTL 19mm | Standard M12 mount and ultra-short TTL, making it ideal for compact device integration. |
Three Core Competitive Advantages of the JSD3428
1. <-1% Ultra-Low Optical Distortion: Empowering Precision Measurement and Recognition
Traditional wide-angle lenses usually suffer from severe barrel distortion, which warps objects at the edge of the frame. This deformation can be fatal for systems relying on precise recognition and measurement, such as QR/barcode scanners, industrial inspection systems, and facial recognition access control.
The JSD3428 utilizes highly precise optical design to suppress physical distortion to less than -1%.
Technical Advantage: The backend processor does not need to waste computing power on software de-warping algorithms. This enables zero-latency image transmission while significantly lowering system power consumption and computing costs.
2. 5MP HD Resolving Power, Tailored for Large 1/2.5" Sensors
The JSD3428 supports high-resolution output up to 5MP and features an optical structure optimized specifically for 1/2.5" formats. This larger light-sensing area, combined with 5MP clarity, allows the lens to output high-contrast, low-noise images with crisp edges even in low-light or complex lighting environments. This provides premium, high-definition raw images for AI visual algorithms.
3. Innovative 2G2P Structure: The Standard for Lightweight and Cost-Effective Design
The lens adopts a hybrid configuration of 2 glass elements and 2 aspherical plastic elements (2G2P).
No Compromise on Performance: By leveraging the powerful aberration-correction capabilities of aspherical plastic lenses, the design reduces the overall element count while successfully containing distortion within 1%.
Cost and Weight Benefits: Compared to full-glass lenses, the 2G2P structure drastically cuts down the lens's overall weight and production costs, offering a highly competitive price-to-performance advantage for mass-production projects.
Recommended Applications
Thanks to its standard M12 mount and an ultra-short TTL (Total Track Length) of just 19mm, the JSD3428 seamlessly integrates into space-constrained smart terminals:
Smart Commercial Displays & Office Tech: 4K/HD video conferencing cameras, desktop collaboration devices, and document scanners.
New Retail & Intelligent Access Control: Barcode/payment terminals (such as self-checkout kiosks), facial recognition access control, and all-in-one identity verification machines.
Industrial Vision & Robotics: Precision navigation for AGVs, production line inspections, and barcode/tilt-angle recognition systems.
Smart Home: Premium smart peepholes, video doorbells, and home security cameras.
The JSD3428 is a mature 5MP lens solution that seamlessly blends ultra-low distortion (<-1%), a wide field of view (96°), and an ultra-thin, compact footprint (TTL 19mm). Backed by its innovative 2G2P architecture, it delivers industrial-grade image quality while unlocking massive cost advantages.
If you are sourcing a wide-angle lens for your project that eliminates the need for algorithm correction, provides high sharpness, and fits a budget-friendly framework, the JSD3428 is undoubtedly your optimal choice.
