摘　　要：本文以荧光分光光度计中单色器为例,采用蒙特卡洛方法进行波长补偿校正,即利用计算机生成大量的随机数来估算波长准确度补偿曲线的参数值,这些参数满足该补偿曲线上的点到波长校正点有最小的偏差。该方法克服了光机结构的误差所带来的影响,降低了调试成本。实验结果表明:经过波长校正单色器波长准确度误差小于±0.2nm,验证了蒙特卡洛方法在光栅单色器波长正中应用的可行性,为校准单色器波长提供了一种新的方法。The Monte Carlo method（MCM）for wavelength compensation correction was proposed and confirmed through a monochromator of fluorescence speetrophotometer. A large number of random data were generated by MCM to estimate the parameter values of the wavelength accuracy compensation curve using a computer, by which the calibration point-to-wavelength of the curve with the minimum deviation were satisfied. The influence of the error from the original optical mechanism structure was overcomed, the debugging costs were reduced with good results achieved. The experimental results showed that the wavelength accuracy error of the monochromator was less than ± 0.2nm after wavelength correction, which verified the feasibility of the Monte Carlo method （MCM） for the calibration of the wavelength accuracy of the monochromator.
