摘要: Abstract Realization of the absolute spectral irradiance responsivity photodetectors in A/W/cm2 is a fundamental requirement for many photometric, radiometric and colorimetric applications. This work aimed to develop standardized setup realizing range 500 nm–950 nm at National Institute Standards (NIS), Egypt. A silicon trap detector, calibrated against primary standard cryogenic radiometer, used as transfer calibration S2281 Hamamatsu photodiode, working standard, using lamp-double monochromator based system. The accompanied uncertainty components affecting measurements were investigated.
