Abstract

The aim of this paper is to promote the accuracy of the quantity for spectral irradiance of standard lamps at transferring, optimize the calibration uncertainty of ultraviolet irradiance, analyze and solve the problem which will effect the measuring course of ultraviolet irradiance, and provide reliable calibration standard for application areas. The main contents include: 1. Put forward a new three segment fitting function of spectral irradiance of standard lamp and an optimizing method for non-linear parameter. Compare relative errors of different curve fitting methods by a new successive error analysis method. The relative deviation of the new curve fitting function is: 0.27% between 250nm and 2500nm which is acceptable comparing to the uncertainty of national primary standard of spectral irradiance lamp. 2. Through a new designed measurement system for cosine response property of UV radiometers, we do some measuring experiments to 21 kinds of UV radiometers and calculate the relative deviation of each UV meters. By measuring experiments we can understand the cosine response property of UV radiometers exactly and do cosine compensation accordingly. 3. Design and fulfill an experimental system to reflect the measuring errors of UV radiometers when measuring sources and calibrated sources are mismatched. Calculate the spectral mismatch correction factor and spectral matching characteristic factor to modify the measuring data.
