absorptiometer
n. C2 Proficiency ab·sorp·tiome·ter
n. a scientific tool used to measure how much light or radiation is absorbed by a material. It helps scientists understand how different substances interact with light.
n. an instrument designed to measure the degree to which a substance absorbs electromagnetic radiation, such as light or X-rays. Often used in spectroscopy to determine the concentration of a chemical in a solution.
The scientist used an absorptiometer to test the sample.
Researchers placed the new solar panel in front of an absorptiometer to measure how much sunlight it could capture.
By analyzing the data from the absorptiometer, the team was able to identify the specific wavelengths of light that the plant's leaves were most efficient at absorbing.
