SK Infrared unlocks the power of next-generation infrared technology, crafting custom detectors and imaging solutions for unparalleled performance across a diverse set of applications.
Infrared technology is extensively used for threat detection and targeting, providing significant tactical advantage by allowing operation in low-visibility conditions. It enhances situational awareness, and provides aerial reconnaissance, tracking movements, and monitoring field conditions.
Infrared sensors, including IR cameras and LiDAR, enable autonomous vehicles and robots to navigate, detect objects, and operate with high sensitivity in various conditions. Satellites use infrared imaging and spectroscopy to analyze greenhouse gases, measure ocean temperature, and detect contaminant signatures in our food supply.
Infrared-equipped drones are used for monitoring large areas, such as forests, urban farming, or livestock health, providing real-time reflective and thermal imagery for stress, moisture and growth patterns. Infrared technology enhances agricultural productivity by enabling early detection of problems, improving resource efficiency, and supporting sustainable farming practices.
Telescopes like the James Webb Space Telescope (JWST) and Spitzer Space Telescope capture deep-space images, detecting galaxies billions of light-years away, using infrared imaging. Infrared spectroscopy can detect and measure environments on other planets, forming stars, and distant galaxies.
Infrared imaging is essential for monitoring and enhancing operations, providing non-invasive sensing, and detecting hidden hazards in various environments. Infrared technology is commonly used for quality control, industrial processes, predictive maintenance, and real-time data capture in low-light or no-light conditions.
