The markets for industrial automation, smart security, and consumer smart devices are booming, and with that comes stricter demands on imaging systems: they need higher resolution to capture fine details, but also a smaller form factor for easier integration. The JSD1326 lens meets these mainstream needs perfectly, combining 16MP high resolution, a 105° wide field of view, and an ultra-short TTL (Total Track Length) of just 22.8mm. It offers an ideal vision solution for a variety of applications.

The Perfect Balance of Ultra-Short TTL and High Resolution

The standout feature of the JSD1326 is its unique combination of a 22.8mm ultra-short TTL and 16MP high resolution. Traditional high-resolution lenses often come with longer physical dimensions, but the JSD1326 manages to pack 16MP into a body that’s only 22.8mm long. This breakthrough design gives it a clear edge in space-sensitive applications.

The lens supports 16-megapixel high resolution, meeting today’s strict requirements for image detail. Whether it’s spotting tiny defects in industrial inspections or capturing facial features in security monitoring, the high resolution ensures the image stays usable and analyzable. Its 7.86mm image circle is optimized for 1/2.3-inch sensors, delivering uniform brightness and sharpness from the center all the way to the edges.

Optically, the JSD1326 uses a 7-element construction (including IR-cut glass), balancing high performance with a compact structure. The 3.56mm focal length provides a 105° diagonal field of view (DFOV), which is wide enough to cover more area with fewer cameras.

Advantages of the Ultra-Short TTL Design

The 22.8mm ultra-short TTL isn’t just a number—it brings real benefits. The compact design makes it easy to integrate into tight embedded devices, which is ideal for drones, portable gadgets, and embedded systems where size and weight matter.

In industrial vision inspection, the short TTL lets the lens fit into limited spaces like robotic arms or automated equipment, while the 16MP resolution keeps inspections accurate. For smart security cameras, the short TTL allows for smaller, more discreet designs without sacrificing image quality.

In drones and robotics, being small and lightweight is critical. The JSD1326 delivers on that without compromising image quality. Its F2.5 aperture provides good light-gathering capability, so even in low-light conditions, you still get usable, well-exposed footage.

Wide-Ranging Applications

The JSD1326’s features make it a great fit for many fields:

Industrial Vision Inspection: High resolution is perfect for precise measurement and detecting tiny defects, while the short TTL enables easy integration into automated equipment.

Smart Security Monitoring: The 105° wide angle covers a broad area, and 16MP ensures plenty of detail for later analysis.

Consumer Electronics: Think smart home cameras or dash cams—its compact size and high performance make it a solid choice for product upgrades.

Drones and Robotics: The short TTL and light weight meet the demand for miniaturization.

Innovative Design

The JSD1326’s performance stems from several technical innovations. Optically, it uses precise optical calculations to correct barrel distortion and edge astigmatism, common issues in wide-angle lenses. The lenses are made of high-transmittance optical glass, which cuts down on dispersion and reflection, boosting contrast and color accuracy.

Mechanically, the lens features a compact, optimized arrangement of elements to minimize size without sacrificing optical performance. This focus on achieving the best optical quality in a small space aligns with the design philosophy of other high-end brands in the industry.

The JSD1326 keeps distortion under 16.5%—a solid level of control for a wide-angle lens. This ensures geometric accuracy in the image, which is crucial for measurement and recognition tasks
