In the world of optical engineering, physics is usually a strict master. You typically have to choose: do you want a high-resolution, large-sensor lens, or do you want something tiny?

The JSD3840 just walked into the room and said, "I'll take both."

We are rewriting the rules of compact optics. By squeezing professional-grade performance into a form factor that fits on the tip of your finger, the JSD3840 is the hero that embedded vision systems have been waiting for.

15.8mm: The Magic Number

Let's talk about TTL (Total Track Length).

For the JSD3840, it is a mere 15.8mm.

To put that in perspective, that is shorter than the width of a standard penny. In the past, fitting a lens this short usually meant sacrificing image quality. But we didn't sacrifice a thing. This ultra-low profile makes the JSD3840 the ultimate solution for space-constrained industrial devices, handheld medical scanners, and compact robotic eyes where every millimeter counts.

20 Megapixels in a Mini Package

Don't let the size fool you. Inside that tiny M12 housing, we have packed the resolving power to handle 20 Megapixels.

Designed for the larger 1/1.8" image circle, this lens captures massive amounts of data. It delivers razor-sharp edges and high contrast, ensuring that your high-end sensor isn't bottlenecked by "good enough" glass. It is a pint-sized powerhouse designed to feed the most demanding AI and machine vision algorithms.

Wide, Flat, and Precise

Usually, short lenses suffer from extreme curvature. Not this one.

The View: With an EFL of 3.76mm, you get a sweeping 100° Field of View.

The Geometry: We achieved <0.4% Distortion.

This is the "Holy Grail" of compact optical design: a wide angle that doesn't look like a fishbowl. Whether you are measuring dimensions on a production line or mapping a room, the JSD3840 delivers straight lines and accurate spatial data right out of the box.

It is built for engineers who build the future. With a fixed F/4.0 aperture, it provides the deep depth of field necessary for:

Automated Optical Inspection (AOI)

Biometric Identification

Drone Surveying

Advanced Robotics

Why compromise? You no longer have to build bulky housing just to get high resolution.

With the JSD3840, you get the 20MP clarity you need, the 1/1.8" sensor coverage you want, and the 15.8mm TTL that your mechanical engineer dreams about.

Small size. Giant performance.
