Grainy video is a deal-breaker. Washed-out colors look unprofessional. In the world of high-end video conferencing and smart monitoring, the sensor is only half the battle.

Your expensive 4K sensor needs a partner. It needs the JSD3840.

Putting a cheap piece of glass on a premium sensor is a tragedy. Let’s fix that. Here is why this specific lens is the game-changer for your next optical design.

Big Glass for Big Sensors

Standard webcams use tiny sensors. High-end devices use 1/1.8" sensors. That extra surface area captures more light and better dynamic range.

The JSD3840 is built specifically for this 1/1.8" Image Circle. It covers the entire sensor area. No dark corners. No vignetting. You get the full performance your hardware is capable of delivering.

Beyond 4K Clarity

4K video requires about 8 megapixels. This lens laughs at that.

It supports a massive 20MP resolution. The glass resolves details far beyond the standard 4K requirement. This allows for lossless digital zooming. Crop into a speaker's face. Zoom in on a whiteboard. The image stays razor-sharp.

Wide Angle, Zero Weirdness

Conference rooms are often small. You need to fit everyone in the frame.

The 100° Field of View captures the whole table. Usually, wide angles create a "fish-eye" effect. Walls look curved. People on the edge look stretched.

The JSD3840 keeps it real. Distortion is less than 0.4%. That is practically zero. The room looks natural. Straight lines remain straight. Reality is preserved.

The Sweet Spot Specs

Industrial design demands compact components.

Thread: Industry-standard M12. Easy integration.

Size: A TTL of 15.8mm. It fits inside sleek, modern housings.

Focus: EFL 3.76mm combined with F/4.0 aperture.

This F/4.0 aperture is crucial. It provides a deep depth of field. The person sitting two feet away is sharp. The presentation screen ten feet away is sharp. No hunting for focus..
