SWIR (Short wave Infrared) / IR-B LED chips

Description

Short wave infrared (SWIR) LED chips emit light in the wavelength range of 1.4 to 3 micrometers, which is shorter than the wavelength of the near-infrared (NIR) light. SWIR LEDs are typically used in sensing applications, such as spectroscopy, machine vision, and surveillance, where they can penetrate certain materials and detect chemical or physical properties that are not visible to the naked eye.

SWIR LEDs can be made from a variety of materials, such as indium gallium arsenide (InGaAs), indium phosphide (InP), and mercury cadmium telluride (HgCdTe). These materials are chosen because they have a bandgap that allows them to emit light in the SWIR range.

IR-B LEDs, on the other hand, emit light in the near-infrared range, specifically in the wavelength range of 750 to 1400 nanometers. They are commonly used for applications such as remote controls, security cameras, and optical communications.

In summary, SWIR and IR-B LEDs are two different types of LEDs that emit light in different parts of the infrared spectrum. SWIR LEDs emit light in the short wave infrared range, while IR-B LEDs emit light in the near-infrared range.
