The Preliminary Discussion of Bandwidth Correction Methods for Spectral Irradiance Measurement of Deuterium Lamp

摘要

Deuterium lamp is used as the transfer standard of air-UV spectral irradiance (200nm to 400nm). The CCPR-Kl.b comparison of spectral irradiance 200nm to 350nm took deuterium lamp as transfer standard lamp. Spectral irradiance is measured by a spectroradiometer with finite bandwidth. The bandwidth can cause measurement error. In order to correct the measurement error, we apply SS and DO bandwidth correction methods to the spectrum of Deuterium lamp. We obtain the correction effect preliminarily.
