测试光纤的几何尺寸己有不少文章介绍,本文介绍一种更简使的方法,此方法不仅设备简单,观测方便,且测试精度也很理想。众所周知,测试光纤几何尺寸,首先要观察到芯层和外包层图象,这里将介绍一种能观察到清晰图象的简易方法。方法取长度大于5cm光纤一根,用火柴烧去光纤涂层,小心擦去焦渣,目的是使光线能顺利地从包层外侧进入光纤,将去焦渣后
Testing the geometry of optical fiber has been a lot of articles, this article describes a more simple method, this method not only equipment is simple, easy to observe, and the test accuracy is also very good. As we all know, to test the optical fiber geometry, we must first observe the core layer and the outer cladding image. Here we will introduce an easy way to observe a clear image. Methods Take a fiber length greater than 5cm, with a match to burn away the optical fiber coating, carefully wipe the cinder residue, the purpose is to make the light can be smoothly from the cladding into the optical fiber,
