| 摘 要： | 提出了一种高精度测量玻璃折射率的方法。它克服了传统的最小偏向角方法的缺点，即需要反复调节样品棱镜直到准确位于最小偏向角位置上才能测量。该方法测量精度高、速度快，适用于光电对准式测角仪器，是标准玻璃样块折射率标定的较好方法。同时，它也适用于不可见光波段的折射率标定测量。

| Abstract: | A new method for measuring the refractive index of glass has beenrecommended in this paper. This method corresponds to the conventional method by means of minimum deviation angle, but it needn' t adjusting the sample prism position again and again until the position of minimum deviation angle has been got. Because of the stationary position of sample, this method will have features of high precision and rapid testing. It is suitable for operating on the precision goniometer with photoelectrical alignment. This is a suitable method for the calibration of refractive index of standard glass block. Moreover, it may be applied to the refractive index measurement of glass for invisible spectral lines. |
