In order to provide radiance reference based on standard detector and improve the calibration accuracy of remote sensor, a multi-band radiance standard transfer detector (MRSTD) based on trap structure has been developed. There are eight channels in MRSTD and the aperation wavelengths of MRSTD are from 400 to 1000 nm. A Si trap detector is used for radiometric power measurement, an interference filter is used to limit the spectral band of the incident light, and a field stop and an aperture stop are used to limit receiving area and solid angle of the input flux. A weak current detection circuit is designed to measure the photocurrent of the detector accurately. The filter and the detector are temperature controlled by a closed-loop control system. The principle and development process of the facility are introduced and the uncertainties of its absolute spectral radiance responsivity are evaluated in detail. The relative uncertainty of MRSTD is less than 1.26%.
