Absolute radiometers measure total radiometric power. These are used primarily in precision testing and measurement applications in research and development.

Absolute radiometers measure the total incident power over all wavelength ranges and directions in a given area; they measure not just the direct power from the energy source, but also the reflections, refractions and scatterings from the environment. An absolute radiometer can provide detailed information about the characteristics of an incident source of radiation and its environment.

Absolute radiometers are used for measurements where higher precision is required and environment conditions must be carefully considered. For example, absolute radiometers are used to measure the spectral characteristics of light sources for medical and scientific purposes, such as light therapy. They are also used to measure the radiation from energy sources such as the sun, and to measure the spectral energy distribution of the atmosphere.

Absolute radiometers are typically either portable or stationary. Portable absolute radiometers are generally used in field measurements, while stationary absolute radiometers are typically used in laboratory settings. Absolute radiometers typically come with a variety of accessories, such as calibration filters and sample holders, to ensure accuracy and repeatability of measurements.

In conclusion, absolute radiometers are used for precision measurement and testing applications in research and development. They are able to measure the total incident power over all wavelength ranges and directions in a given area, and they come with a variety of accessories to ensure accuracy and repeatability of measurements.
