Infrared emitters convert drive current into 850 nm or 940 nm near-infrared radiation for machine vision, sensing, and covert illumination. QUEENDOM manufactures IR LEDs in every format: 3–10 mm DIP lamps, surface-mount packages, and high-power ceramics delivering hundreds of milliwatts of radiometric output.The wavelength choice follows the application: 850 nm gives 30–40% higher radiant intensity and strong camera response for CCTV illuminators and license-plate capture, while 940 nm is completely invisible to the eye for remote controls, presence detection, and security beams. Pulse ratings reach 1 A (≤100 µs, 1% duty) for burst signaling. Pair emitters with our matched photodiodes for reliable transmitter-receiver links. Wavelength shift over temperature and drive curves are documented in the IR datasheet downloads.

Product Series by Wavelength 1. Near-Infrared (NIR) LEDs — 710 nm to 940 nm Technology: Aluminum Gallium Arsenide (AlGaAs) / Gallium Arsenide (GaAs) Package: 3mm, 5mm, 8mm, 10mm DIP; SMD 2835, 3535, etc. Applications: CCTV night vision, remote controls, photoelectric sensors, wellness devices. 2. Short-Wave Infrared (SWIR) Emitters — 1050 nm to 2010 nm Technology: Indium Gallium Arsenide (InGaAs) laser diodes or thermal emitters Package: TO-18, TO-56, Butterfly, or bare die (requires driver & TEC) Applications: Gas analysis (CO₂, CH₄), moisture detection, semiconductor inspection, R&D. Key Notes Wavelengths above 1000 nm are not achievable with standard LED technology. SWIR products require constant-current drivers and often thermoelectric cooling (TEC). All NIR LEDs comply with RoHS/REACH; SWIR components follow industrial laser safety standards (IEC 60825).
