The System of High Accuracy UV Spectral Radiation System Based on Quartz Retarder
In order to achieved the coaxial optical designed unit for UV spectral radiation detecting and visible observation telescope, UV / visible beam splitter and four pieces of the quartz retarder were used, and a lock-in amplifier was used in the electical system to advance the accuracy of measurement. To ensure the precision measurement deteced,the phase-sensitive detector function can be adjustable. So the maximum residual polarization of the incident light for wavelength from 200 nm to 380 nm can be down to 3%. The output value of instrument is not more than 10 mV before each measurement , so it can be ensured that the stability of the measured radiation spectrum is less than 1%.
