An actinometer is a device used to measure the intensity of incident radiation on a surface. It is typically used to measure the amount of light or ultraviolet radiation that is present in a given environment. The device works by measuring the amount of energy that is absorbed by a material, such as a blackened metal plate, when exposed to radiation. The amount of energy absorbed is then converted into a numerical value which can be used to calculate the intensity of the incident radiation.
