Yingfeng is among the few specialized manufacturers offering emitters in the extended NIR wavelength, also known as SWIR (Short Wavelength Infrared), covering a range from 1000nm to 3000nm. We also now provide mid-wave infrared (MWIR) LEDs, with wavelengths spanning from 3000nm to 5000nm (3µm to 5µm). Our standard product lineup includes wavelengths from 1000nm to 4300nm, designed for high-power applications with operating currents from 20mA to 1A.

Yingfeng SWIR and MWIR LED series come in diverse package types, including ATLAS hermetic SMD, metal hermetic TO-cans, standard surface mount devices (SMD), plastic molded through-hole, chip-scale packaging (CSP), chip-on-board (COB), starboards, linear boards, and custom options tailored to meet OEM specifications. These short and mid-wave IR emitters deliver optimized performance for applications such as gas detection, moisture sensing, medical diagnostics, flame detection, chemical analysis, fiber optic communication, military uses, optical switching, and material sorting. The SWIR range, also referred to as Extended NIR or NIR II, provides crucial capabilities for cutting-edge technological and industrial applications.
