Ultraviolet (UV) detectors are devices designed to sense and measure ultraviolet radiation, which is a type of electromagnetic radiation with wavelengths shorter than visible light. These detectors are commonly used in various applications, including environmental monitoring, medical diagnostics, and industrial processes, to ensure safety and compliance with regulations. UV detectors can operate using different technologies, such as photodiodes, photomultiplier tubes, or solid-state sensors. They convert UV light into an electrical signal, allowing for the quantification of UV exposure. This information is crucial for protecting against harmful effects, such as skin damage and eye injury, caused by excessive UV radiation.
