Optical sensors are used to detect various things using visible light and invisible light. It is used as a matter of course in daily life, such as remote control of TV and opening and closing of automatic door. In recent years, optical sensors have been used to improve the capabilities of devices such as communications, medical, industrial, household, automotive, and healthcare devices, and are expected to be used in a wider range of fields.
ROHM manufactures light emitting devices with various wavelengths such as infrared light emitting diodes and VCSELs, high sensitivity and high reliability phototransistors, light receiving devices such as transmissive photointerrupters, and light receiving and emitting modules such as reflective photosensors (photoreflectors). We have a wide range of sensor ICs and other products to meet the diverse needs of the market.
