Braden Czapla (Fed)
Braden Czapla is a mechanical engineer in the Dimensional Metrology Group, located on NIST’s Gaithersburg campus. He is the technical lead for the Sphere Diameter by Interferometry measurement service. His research interests lie in building and evaluating interferometers for measuring dimensional artifacts (spheres, gage blocks, etc.). He also works with terrestrial laser scanner systems, focusing on quantifying the contributions to uncertainty in dimensional measurements due to the optical properties of the measured object.
Prior to joining the Dimensional Metrology Group, Braden was an NRC Postdoctoral Research Associate in the Remote Sensing Group. His postdoctoral work focused on measuring broadband complex refractive indices of materials and making improvements to the Fourier transform infrared spectrophotometry (FTIS) facility. Braden also has expertise in infrared optical properties of materials, development of spectrophotometric equipment, radiative heat transfer, near-field radiative heat transfer, and passive radiative cooling.
