SWIR, aka Short-Wave Infrared (IR), is swiftly becoming the best option for applications that do not involve visible lighting. The wavelengths of SWIR are in the 1,050 to 2,500 nm range. That means they are invisible to the naked eye. Yet, in some cases, this field can fall between the range of visible lighting and thermal imaging.
In fact, the SWIR spectral band is close to visible light. This enables imaging qualities (e.g., resolution and contrast) while allowing it to reveal invisible elements. Simply put, the range allows SWIR LEDs to have a unique set of applications. That includes industrial, machine vision, and remote sensing purposes. It also encompasses surveillance and even ambient light applications.
Short-Wavelength infrared (SWIR) sensors and LEDs can be used for controlling image transmission through opaque materials. That includes silicon, plastics, and others. Additionally, they can unveil elements or substances such as water, collagen, lipids, alcohol, and more. High-power LEDS can also benefit various other applications, from food inspection and analysis to narcotics testing, healthcare, biomedical, and wearable devices. Overall, SWIR LEDs provide high efficiency and power with plenty of options for customization and mass production.
