A new method for calibrating monochromatic uniform planar source is proposed. In view of present need, traditional calibration method is improved and a new system is constructed. System uncertainty of each parameters is also evaluated. The overall performance of monochromatic uniform planar source can be evaluated perfectly by calibrating stability, uniformity, output power and output wavelength. Experimental results show that, between 300 nm and 1100 nm, stability of monochromatic uniform planar source is 0.47%, nonuniformity is 0.9%, calibration coefficient of output wavelength is a=1.0016, b=-1.6755, respectively. According to the data obtained, this system can completely meet the demand of calibrating monochromatic uniform planar source and has an important significance for manufacturers and users.
