QUESTION: Do you have any documentation available on controlling end-face geometry characteristics of PC ferrules?
ANSWER:
Understanding and controlling end-face geometry characteristics of PC ferrules is fairly simple and intuitive. A radius is……a radius. And if you want to increase the radius of a ferrule, you simply need to polish with less pressure, or use a harder backing pad while polishing. If you want to decrease the radius, you need to polish with more pressure, or use a softer backing pad.
The Apex is determined simply by how perpendicular the ferrule is to the polishing surface—–a ferrule with a lower Apex value means the ferrule is sitting more perpendicular to the polishing surface than a ferrule with a higher Apex value. Simple, easy to understand and apply.
