Optical Sensors Market Size reached US$ 22.12 billion in 2024 and is expected to reach US$ 55.60 billion by 2032, growing with a CAGR of 12.21% during the forecast period 2025-2032.

An optical sensor is a device that detects and measures light or infrared rays and converts them into an electrical signal. These sensors are essential components in a wide range of modern technologies, enabling devices to "see" or sense their environment. They work by transmitting and receiving light, and analyzing how the light is affected by an object or environment to gather information.
