Precision UV Sensor is composed of zinc oxide

ZnO ultraviolet UV sensor makes it possible to detect UV rays based on frequency band, allowing user to obtain detailed information and take appropriate countermeasures against UV rays.

No optical filter is required, and thin film made of zinc oxide (ZnO) material becomes transparent under visible light and opaque under UV rays. Control of absorption wavelength range based on specific material composition makes it possible to perform sensing at UV-A/-B ranges.
