We have all seen it: that warped, spherical "bubble" look typical of wide-angle lenses. It might be fun for skateboarding videos, but in the world of professional imaging, industrial inspection, and high-end security, the "fisheye effect" is a disaster. It bends straight lines, distorts dimensions, and confuses AI algorithms.

Stop fighting with distortion. It’s time to straighten things out.

Meet the JSD3122, the M12 lens that proves you can have a wide view without bending reality. Designed strictly for professional and industrial applications, this lens delivers a "what you see is what you get" experience.

Here is why the JSD3122 is the antidote to the fisheye blues.

1. The "Linear" Revolution (Distortion < -1.54%)

The headline feature of the JSD3122 is its incredible geometric precision. While standard wide lenses can have distortion rates of 10% to 20%, the JSD3122 keeps optical distortion locked down at <-1.54%.

The Result? Door frames stay vertical. Conveyor belts look straight. Barcodes remain rectangular.

The Benefit: If you are developing systems for Computer Vision or Biometric Recognition, this lens eliminates the need for heavy software de-warping, saving processing power and reducing latency.

2. A Wide 92° FoV—Naturally

You need to see the whole scene, but you don't want it to look like a peep-hole.
With a 92° Field of View (FoV) and an EFL of 3.94mm, the JSD3122 offers a broad, comfortable perspective. It is wide enough to capture a full workspace, a meeting room, or a traffic lane, but tight enough to maintain high pixel density on your subject. It’s the perfect balance of coverage and clarity.

3. Big Sensor Power (1/2" Image Circle)

Most "low distortion" M12 lenses on the market are tiny, designed for small 1/4" mobile sensors. The JSD3122 is in a different weight class.
It features a generous 1/2" Image Circle. This allows professional integrators to use larger, high-performance sensors (like global shutter industrial sensors) to capture more light and detail, without suffering from dark corners or vignetting.

4. 12MP Resolution: Clarity in Every Corner

A flat image is useless if it’s blurry. The JSD3122 is rated for 12MP Resolution, ensuring that your high-definition sensors are fed with sharp, crisp optical data. From the center of the frame to the very edges, the image remains distinct—critical for OCR (Optical Character Recognition) and defect detection.

5. Professional Specs for Professional Builds

Bright Aperture: The F/2.2 aperture ensures excellent performance even in dim factory lighting or evening surveillance scenarios.

Compact Integration: Despite its high-end optical glass, it fits into a standard M12 Thread with a TTL (Total Track Length) of just 20.49mm. It’s ready to slot into your existing housing designs.

The Verdict

The JSD3122 is for engineers who demand truth in imaging. Whether you are building smart traffic cameras, industrial scanners, or high-fidelity video conference systems, this lens gives you the wide angle you need without the distortion you hate.

See the world as it really is. Switch to the JSD3122.
