ROHM Develops Compact Surface-Mount Near-Infrared LEDs Featuring Industry-Leading Radiant Intensity

ROHM has expanded its portfolio of surface-mount near-infrared (NIR) LEDs with new compact top-view types. They are optimized for applications such as VR/AR devices, industrial optical sensors, and human detection sensors.

The new lineup consists of six models in three package configurations, including two ultra-compact (1.0mm × 0.6mm), ultra-thin (t=0.2mm) products as part of the PICOLED™ series: SML-P14RW and SML-P14R3W. In addition, there are four variants in the industry-standard (1.6mm × 0.8mm) size, featuring a narrow beam circular lens package (CSL0902RT, CSL0902R3T) and flat lens design that emits light over a wide range (CSL1002RT, CSL1002R3T). Each package is available in two wavelengths, 850nm (860nm for the SML-P14RW) and 940nm, allowing customers various options for their specific application needs. The 850nm wavelength is ideal for phototransistors and camera sensors, making it suitable for high-sensitivity applications such as eye tracking and object detection in VR/AR. At the same time, the 940nm wavelength is less affected by sunlight and does not appear red when emitting light, making it suitable for motion sensors. It is also widely used in biosensing applications such as pulse oximeters to measure blood flow and oxygen saturation (more info).
