SWIR Cameras: What Are They? [Imaging & Application Guide] Short-Wave Infrared (SWIR) imaging opens a window into parts of the light spectrum that are invisible to the human eye. SWIR cameras capture wavelengths typically ranging from 900 to 1700 nanometers, revealing critical insights in industrial inspection, agriculture, defence, and scientific research. As machine vision continues to evolve, SWIR technology is emerging as a powerful solution for advanced imaging challenges. What Are SWIR Cameras? SWIR cameras operate in the short-wave infrared band of the electromagnetic spectrum. Unlike visible light or even long-wave infrared (LWIR), SWIR imaging can penetrate certain materials like silicon, plastic, and textiles, making it ideal for applications where visual inspection is limited. These cameras often use sensors made from Indium Gallium Arsenide (InGaAs), which are highly sensitive in the SWIR range. This unique sensitivity enables clear imaging in low-light or challenging atmospheric conditions such as fog, haze, or smoke. Key Features of SWIR Cameras Material Penetration SWIR cameras have the ability to see through packaging materials, surface coatings, and even silicon wafers. This makes them essential in electronics manufacturing, pharmaceutical packaging inspection, and non-destructive testing environments where traditional…

Understanding GigE Cameras: Interface, Advantages & Future Trends In the world of machine vision, choosing the right camera interface can make or break the efficiency of an imaging system. Whether you’re building a quality inspection solution for a manufacturing line or developing a vision-based AI model, the type of camera you select and how it connects to your system is critical. One interface that continues to stand out for its balance of performance, flexibility, and cost-effectiveness is GigE. In this post, we’ll dive into what GigE cameras are, how they compare to other popular interfaces like USB, CoaXPress, and Camera Link, and why they’re a great option for the future of high-speed, high-resolution imaging. What Are GigE Cameras? GigE cameras are industrial cameras that use Gigabit Ethernet (GigE) technology to transmit image data. GigE is a well-established networking standard (IEEE 802.3) capable of transferring data at up to 1 gigabit per second (1 Gbps) over standard Ethernet cables (CAT5e or CAT6). Unlike USB or Camera Link, GigE allows cameras to transmit data over long distances, up to 100 meters without the need for signal boosters or repeaters. These cameras are…

Time of Flight 3D Camera: What You Need to Know Time of Flight (ToF) technology has transformed depth sensing and 3D imaging by offering a fast, precise, and dependable method for measuring distances. ToF 3D cameras, which rely on this technology, are making significant contributions to 3D machine vision. They are driving advancements in areas like robotics, industrial automation, and consumer electronics. From robotic pick-and-place systems to autonomous navigation, these cameras have become essential in modern industries. What is a Time of Flight 3D Camera? A Time of Flight (ToF) 3D camera determines depth by calculating the time light takes to travel to an object and back—this is the core principle of Time of Flight. These cameras typically feature an infrared light source , a sensor to detect the returning light, and processors that convert the data into a 3D depth map or point cloud. Comparison with Other 3D Imaging Methods Stereo 3D This method utilizes two cameras positioned at slightly different angles to mimic human binocular vision, enabling depth calculation through the process of triangulation. While effective for capturing depth information, it requires precise alignment and intricate calibration to…
