What are the advantages of optical sensor?

Optical sensors offer high sensitivity and accuracy in detecting light and its variations, making them ideal for applications like imaging and spectrometry. They are non-invasive, allowing for real-time monitoring without physical contact, which is beneficial in medical and environmental applications. Additionally, optical sensors can operate over a wide range of wavelengths, enabling versatility across different fields such as telecommunications, automotive, and industrial automation. Their fast response times also make them suitable for high-speed applications.
