Question: How many measurement scientists does it take to screw in an LED lightbulb? Answer: For researchers at the National Institute of Standards and
Measuring large forces, such as the thrust of a rocket engine or the deflection of an aircraft wing, requires well-calibrated force sensors. NIST’s unique
NIST provides the national reference for the calibration of neutron radiation detectors used for personnel protection and for neutron personnel dosimeters.
The certification for all SRM neutral density filters expires after two years. We maintain a program to recertify such filters produced by us. Filters returned
NIST provides calibration of the spectral responsivity and spatial uniformity of photodetectors for use in industrial and government labs. These calibrations
