Caption: The circular patch of carbon nanotubes on a pink silicon backing is one component of NIST's new cryogenic radiometer, shown with a quarter for scale. Gold coating and metal wiring has yet to be added to the chip. The radiometer will simplify and lower the cost of disseminating measurements of laser power.
Usage Restrictions: None
