摘要
Abstract
Primary standard densitometer for visual diffuse transmission density, characterized by hemispherical emitter with optic fiber ( HEWOF) is established. Characterization measurements have showed that the geometric and spectral conditions of this densitometer meet the specifications of ISO 5. Its combined uncertainties are 0. 0015(0 < D < 4. 5) and 0.0054(5.0≤D < 6.0). Taking the advantage of that the composite difhiser can be combined respectively with light source and detection system ,the validity of Helmholtz reciprocity for transmittance measurement is examined .关键词
