Optical chemical sensors are advanced devices designed to detect and measure the presence or concentration of specific chemical substances by analyzing changes in light. These sensors use optical properties such as absorption, fluorescence, reflection, refraction, and light scattering to identify chemical compounds accurately and efficiently. With increasing demand for real-time monitoring, environmental protection, industrial safety, and healthcare diagnostics, optical chemical sensors are becoming an important part of modern sensing technologies. Their high sensitivity, rapid response, and ability to perform measurements without direct electrical contact with the sample make them suitable for a wide range of applications.
