SWIR LED signifie “Short-Wave Infrared Light Emitting Diode.” SWIR LEDs emit light in the short-wave infrared spectrum, which typically ranges from approximately 900 nanometers to 2500 nanomètres. These LEDs are used in various applications such as surveillance, vision nocturne, machine vision, spectroscopy, and industrial imaging. SWIR LEDs offer advantages such as low power consumption, compact size, and the ability to penetrate certain materials that are opaque to visible light. They are particularly useful in environments where conventional lighting sources may not be suitable or effective.
