The sphere\u2019s interior coating, typically composed of barium sulfate (BaSO\u2084) or polytetrafluoroethylene (PTFE), ensures high reflectivity (&gt;95%) across visible and near-infrared spectra. Detectors mounted at the sphere\u2019s exit port measure the integrated flux, enabling calculations of total luminous flux, colorimetric parameters, and spectral power distribution.  <\/p>\n<h2>Key
