| Abstract: | A spectral responsivity scale has established at near infrared(944-1589nm)three wavelengths with uncertainty less than 0.7%.The scale is maintained on InGaAs trap transfer standard detectors which were directly calibrated against the cryogenic radiometer.This paper describes how the scale is established,and analyses the component uncertainties which contribute to total uncertainty associated with the scale. |
