With the rise of new, energy-efficient solid-state lighting (SSL) systems has come the need for new performance metrics and measurement methods to address their
SIRCUS is a reference facility for the calibration of detectors and radiometers for spectral irradiance responsivity and spectral radiance responsivity across
NIST provides calibration of the spectral responsivity and spatial uniformity of photodetectors for use in industrial and government labs. These calibrations
This project develops methods for very accurate measurements of thermal noise and provides support for such measurements in the communications and electronics
The NIST Thermodynamic Metrology Group maintains and develops national standards of temperature (in the range 0.65 K to 2011 K), and supports calibration of all
U.S. manufacturers have contended for decades that traceability to national standards for industrial irradiation applications is best achieved by services based
Standard Reference Materials® ( SRMs® ) and commercially produced, NIST-traceable materials for UV/visible/NIR spectrophotometry are transfer standards that
We have developed several portable radiometers to transfer the primary detector-based scales for optical power, radiance, and irradiance in the infrared
Imagine how much safer a fire fighter's job would be if it were possible for a robot to navigate in a burning building and locate those in need of assistance
