Question for the Fiber Design and Manufacturing Expert.  Do you have tips for those having difficulty achieving straight preforms?



This is definitely an art and requires some practice. I have found procedures that deliver a reproducible technique. For example, setting the optimum burner H2/O2 ratio can prevent preform sagging and glass burn-off during collapse, which leads to variability later in the process. 

Update: This and other tips are covered in the blog, Attention specialty fiber manufacturers: Take advantage of FOC’s preform fabrication consulting to troubleshoot your system and achieve reproducibility and high yields
