In the world of embedded vision and industrial design, space is the ultimate luxury. Engineers are constantly fighting a losing battle: they want bigger sensors for better data, but they have less and less room to fit the optics.

Usually, if you want to cover a massive 1-inch (1/1") sensor, you are stuck with a bulky C-Mount lens that sticks out like a sore thumb.

But what if you could squeeze that "big lens performance" into a tiny package? Meet the JSD6628. It’s the optical equivalent of a magic trick, delivering 1-inch sensor coverage with a Total Track Length (TTL) of just 34.49mm.

Here is how the JSD6628 solves the "Big Sensor, Tiny Box" paradox.

1. Defying Physics: The 34.49mm Miracle

Let’s talk numbers. A TTL of 34.49mm is incredibly short for the optical power packed inside this barrel.
Most lenses capable of covering a 1-inch image circle are long, heavy, and cumbersome. The JSD6628 disrupts this trend. By utilizing high-refractive-index glass and a cutting-edge optical structure, it compresses the light path without crushing the quality.

The Benefit: This allows you to design handheld scanners, compact drones, and tight-space inspection modules that are sleek, lightweight, and aerodynamic.

2. The M16 Sweet Spot

How do you fit a 1-inch optical format into a compact body? You graduate from the standard M12 (S-Mount) but stop short of the bulky C-Mount.
The M16 Thread is the secret weapon here.

Why M16? It provides just enough physical diameter to house the larger glass elements required for a 1-inch image circle, ensuring that light reaches the very corners of the sensor.

The Result: You get the light-gathering capability of a large lens with the compact footprint of a board lens.

3. Small Size, Massive Resolution (50MP)

Being small usually means sacrificing performance. Not here. The JSD6628 is rated for 50MP Resolution.
This is critical for modern industrial applications. A small, blurry lens is useless. A small, sharp lens is a game-changer.
Whether you are reading microscopic barcodes or mapping terrain from a drone, the JSD6628 resolves fine details across the entire 102° field of view, proving that "compact" doesn't have to mean "compromise."

4. Wide and True (102° FOV & <3% Distortion)

With a 6.6mm EFL, this lens gives you a wide 102° Field of View. In tight spaces—like inside a machine enclosure—this wide angle is a lifesaver, allowing the camera to see the whole target from a short working distance.
And the cherry on top? Distortion is <3%.
Despite its short, compact nature, it doesn't bend the world like a fisheye. It keeps your data accurate and your straight lines straight.

The Bottom Line

The JSD6628 is a masterclass in spatial efficiency. It was designed for the engineer who looks at a 1-inch sensor and says, "I need to fit this into a device the size of a deck of cards."

With a TTL of 34.49mm, F/2.8 aperture, and 50MP clarity, it doesn't just fit into limited spaces—it dominates them. If you are building the next generation of compact industrial vision systems, the JSD6628 is the lens that fits.
