Space is luxury.

When you are engineering the latest compact security module, a sleek biometric scanner, or an embedded IoT sensor, every millimeter counts. You need a lens that fits inside a slim housing but still delivers high-end optical performance.

Stop compromising. Meet the JSD2112.

This isn't a lens for bulky DSLR cameras. This is a precision optical component designed for integrators and engineers who need to pack massive performance into a tiny footprint.

The "Shorty" Champion: TTL 17.41mm

The headline feature here is the size. With a Total Track Length (TTL) of just 17.41mm, the JSD2112 is incredibly low-profile.

Why it matters: It allows you to design thinner, sleeker devices. Whether it’s a smart doorbell that sits flush against a wall or a drone camera that needs to reduce wind drag, this M12 S-Mount lens fits where others won’t.

Perfect Match for 1/2.8" Sensors

The JSD2112 is optimized to cover an Image Circle of 1/2.7", making it the perfect companion for the popular 1/2.8" sensor format found in most modern industrial and security cameras.
Combined with 5MP Resolution, it ensures that your machine vision algorithms receive crisp, high-definition data—crucial for facial recognition or license plate reading.

F1.2 Aperture: See in the Dark

Usually, making a lens smaller means sacrificing light. Not this time.
We managed to engineer a massive F1.2 Aperture into this compact body.

The Benefit: It allows maximum light intake, ensuring your sensors perform exceptionally well in low-light conditions without relying heavily on noisy digital gain.

181° of Total Awareness

With an Effective Focal Length (EFL) of 2.16mm, this lens offers a sweeping 181° Field of View.
It effectively turns your device into an all-seeing eye. Despite this ultra-wide coverage, the optical design keeps Distortion low (<-3.17%), providing a usable image that balances wide coverage with realistic proportions.
