Carbon nanotube forest enhances NIST detector

Facebook X LinkedIn Email
A new ultradark detector that reflects almost no light could lead to vastly improved laser power measurement. Thermal detectors measure laser power by converting photons into heat, and National Institute of Standards and Technology (NIST) physicists found that applying a black coating made of carbon nanotubes optimizes the performance of these detectors. This breakthrough will improve the measurement accuracy of solar cells, satellite-based sensors and optical fiber communications, said Dr. John H. Lehman, a physicist in the optoelectronics division of NIST Boulder Laboratories....Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
