光学玻璃内透过率测试新方法

A new method to measure internal transmittance of optical glass

叙述了采用双样品 ,分别单独测试和计算光学玻璃内透过率的一种新方法。重点叙述了计算公式的理论推导 ,并简要说明了目前采用方法的优缺点。

The new method is to test and calculate internal transmittance of optical glass with two samples.The paper focuses on theoretical inference of the calculating formula and briefly illustrates the advantages and disadvantages of the method.
