In many industries, near-infrared (NIR) LEDs are transforming how machines illuminate and sense. These LEDs emit invisible light (700–1000 nm) and are extremely efficient, contributing to sustainability. For example, Marktech Optoelectronics notes their NIR LED designs *”minimize energy use and carbon footprint.”* In practice, switching to NIR LED lighting and sensing can dramatically cut power…

Near-infrared LEDs in medical devices are quietly transforming patient care, from high-tech hospital equipment to everyday health monitors. These invisible wavelengths of light give medical designers new ways to sense and heal the human body without invasive procedures. As detailed in our Near-Infrared (NIR) LED Guide, a near-IR LED (also called an infrared diode) emits…
