| 摘 要： | 讨论了几种光学玻璃折射率绝对测量方法的特点。指出传统的最小偏向角法的不足之处。提出了一种所谓任意偏折法的绝对测量方法。在对四种方法互相比较的基础上,指出用任意偏折法对基准传递样块进行折射率标定是较好方法。文中还给出了任意偏折法的测量步骤和测量实例。

| Abstract: | This paper stated four typical absolute methods used formeasuring the refractive index of optical glass. It pointed out the dis-advantage in the method of the traditional minimum deviation angle,and introcluced a method called as arbitrary refractive deviation. Themethod of arbitrary refractive deviation is thought of as an appropriatemethod for calibrating refractive index of standard glass blocks on thebasis of comparison of four methods. The measuring procedure and anexample of this method were given in this paper. |
