标准摘要
[中文适用范围]： 本文件规定了一种使用干涉法测定光学玻璃折射率温度系数的测试方法。光学玻璃的温度变化会导致光程长度的变化。光程长度的变化可以用干涉仪根据干涉条纹的明/暗变化周期数来测量。本文件定义了一种测试方法，用于测量样品温度连续变化时折射率的变化量。指定测量方法的预期温度范围是任意范围。指定测量方法的预期波长范围为 365 nm 至 1 014 nm。指定测量方法的预期精度在 1 × 10-6 K-1 以内。 [外文原描述]： This document specifies a test method for the temperature coefficient of refractive index of optical glass using interferometry. Temperature changes in optical glass lead to changes in the optical path length. The change in optical path length can be measured with an interferometer using the number of cycles of light/dark change of the interference stripe. This document defines a test method to measure the amount of change in the refractive index when the temperature of the specimen is changed continuously. The intended temperature range for the specified measurement method is an arbitrary range. The intended wavelength range for the specified measurement method is 365 nm to 1 014 nm. The intended accuracy for the specified measurement method is within 1 × 10 -6 K -1 .
