Don’t let its small size fool you—this pinhole lens packs some real optical muscle. At its heart is a 1/2.7-inch image sensor, which gives you a solid foundation for good image quality. Paired with a 7.7mm image circle, it makes sure light spreads evenly across the sensor, so you don’t get dark corners around the edges.

With a 3.56mm focal length, the lens offers a 30° field of view (FOV)—just right for mid-range close-ups or checking fine details. The wide F2.0 aperture pulls in plenty of light, so even in dim settings, your footage stays bright and usable. That’s a real plus when working in low-light conditions.

What really stands out is the super-short 22.8mm total track length (TTL). This compact design means it can slip into tight spaces easily. And with a standard M12 mount, it’s simple to install or swap out, all without giving up sturdiness .

Depending on your needs, they can tailor the focal length, aperture, TTL, or mount type. Whether it’s for a specific working distance, light condition, or device integration, they’ll make sure it fits

Where It Shines: Solving Real Problems

Thanks to its tiny size and HD imaging, this little lens tackles challenges across a range of fields:

Industrial Endoscopy: Its small build lets it peek inside machinery or pipes where you can’t see otherwise, helping with nondestructive testing and troubleshooting .

Discreet Security: In specialized surveillance where being unnoticed is key, it delivers clear, steady footage without drawing attention .

Smart Device Integration: Think small robots or drones that need vision guidance—it’s a reliable solution when space is tight but image quality matters .

Research & Documentation: Also handy for scientific recording where both size and clarity count .

Compliance and Quality Assurance

It’s important to stress: this product is designed for legitimate uses like industrial inspection and security. The factory clearly states its proper applications and advises customers to use it within legal boundaries .

On the quality side, they’ve built a full control system—from raw material selection to production checks—to ensure reliability and consistent image output. There’s also solid after-sales support to back you up with technical help when needed .

With its 1/2.7-inch sensor, 3MP resolution, F2.0 aperture, and 22.8mm ultra-short TTL, the JSD mini HD pinhole lens strikes a smart balance between being tiny and capable. Whether it’s for industrial probing, professional security, or building into smart devices, going straight to the factory means you get a solution that’s more tailored—and often better value
