ROHM Short-Wavelength Infrared (SWIR) Devices

ROHM has developed a Short-Wavelength Infrared (SWIR) devices in the industry’s smallest class 1608-size (1.6mm × 0.8mm) for portable/wearable/hearable devices requiring material detection.

SWIR is used to detect the presence of substances and their constituent components by taking advantage of characteristics of water, ice, gases, etc. that absorb specific wavelengths, target applications include light sources for blood oxygen saturation and blood glucose measurement devices in the medical fieldAdoption is also anticipated in sensing applications through OLED panels in portable devices, and wearables devices to add health monitoring and other novel functions.

ROHM has established mass production technology for compact 1608-size surface mount SWIR products (light emitting/receiving) by leveraging manufacturing technology cultivated through the mass production of compound semiconductors such as visible and near-infrared LEDs. For the light emitting side, a lineup of 10 LEDs is planned in varying package shapes (molded/lens) and wavelengths (1050nm to 1550nm). And on the light receiving side, 4 photodiode models will be offered in different packages (1608-size / 20125-size (2.0mm × 1.25mm)) and photodetector block size.

The following products are currently in mass production.
・The light emitting side：CSL0901S10 ＆ CSL0901S13
