200～350nm石英窗口氘灯光谱辐照度的绝对定标

ABSOLUTE CALIBRATION OF THE SPECTRAL IRRADIANCE OF QUARTZ WINDOW DEUTERIUM LAMP IN 200-350nm

本文以合肥８００ＭｅＶ电子储存环同步辐射光源作为相对光谱辐射标准，标定了石英窗口氘灯２００～３５０ｎｍ波段的相对光谱分布，利用中国计量院石英卤钨灯光谱辐照度标准光源，完成了３００～３５０ｎｍ波段的绝对定标，并外推出２００～３５０ｎｍ石英窗口氘灯的绝对光谱辐照度，建立了实验室用紫外光谱辐照度传递标准。

In this paper, the relative spectral distribution of a quartz window deuterium lampas spectral irradiance transfer standard in 200- 350um was calibrated based on Hefei 800MeV electron storage ring. By using tungsen halogen spectral irradiance standard source, theabsolute spectral irradiance of the deuterium lamp was determined in 300-350um. Based upon these measurements,the absolute spectral irradiance in 200-350um was obtained throughextrapolation.The transfer standard of spectral irradiance for laboratory was also obtained.
