Optical Sensors

IDT optical sensors portfolio consists of UVA and UVB light sensors, ambient light sensors, RGB color sensors, and proximity sensors. The ambient light sensor ICs (ALS) and proximity sensor ICs enable sophisticated display control in mobile devices. The RGB sensor ICs improve camera flash and picture quality, while the UV sensor ICs provide accurate information about UVA and UVB exposure.

Measuring UVA and UVB Exposure for Improved Wellness

The risks associated with UV rays, whether getting too much or too little, are well-documented. Overexposure can lead to skin cancer, and underexposure can result in seasonal affect disorder (SAD) or low levels of Vitamin D. IDT’s UV sensor ICs accurately sense the UVA and UVB light spectrum, offering consumers a better understanding of their environment so they can monitor and avoid risks associated with UV exposure. In addition to health and wellness applications, the sensor enables "contextual awareness" in applications.
