DOWA launches high-power SMD operating at 1040–1900nm SWIR wavelengths
Dowa Electronic Materials Co Ltd of Tokyo, Japan (a subsidiary of Dowa Holdings Co Ltd) has launched a surface-mountable device (SMD) in the peak wavelength range of 1040–1900nm made with its high-efficiency SWIR (short-wavelength infrared) LEDs. DOWA aims to expand business in the rapidly growing machine vision and healthcare markets.
DOWA claims to be the top manufacturer of SWIR LEDs and indium gallium arsenide (InGaAs) photodiodes, with the world’s largest production capacity and track record. By adding to its product range with SMDs that are in high demand in the machine vision and healthcare markets, DOWA is now able to respond to a wider range of customers.

Compared with LEDs, the radiant power output of DOWA’s SMD is reckoned to be 46% higher in the 1300nm wavelength range used for semiconductor wafer inspection and 36% higher in the 1460nm water absorption wavelength range utilized in food analysis.
In addition to the existing 5mm-square version, DOWA will soon introduce a 3mm-square SMD. The 5mm-square high-power SMD is being showcased at the LASER World of PHOTONICS 2025 event in Munich, Germany (24–27 July).
DOWA says it will continue to aim to advance and broaden its SWIR technologies by improving its product performance and expanding its product offerings to meet evolving market needs.
