Abstract
For more than 20 years, the Berlin-based company sglux GmbH has been producing photodiodes and sensors for measuring UV radiation, as used in many areas of industrial production, medical technology, combustion control and for monitoring UV disinfection processes. The precise detection of the ultraviolet irradiance is of great importance for a controlled and efficient functioning. sglux solves these tasks with SiC-based photodiodes, since 2009 from in-house semiconductor production. SiC photodiodes have an advantage in the detection of UV radiation due to their high band gap of 3.26 eV, as they are insensitive to visible and near-infrared radiation. In addition, SiC photodiodes have very low dark currents, so that even the smallest amounts of radiation can be detected. In the measurement of strong UV radiation, SiC scores with its high resistance to degradation.
