Fiber optic filament is manufactured in both a glass or plastic. The filament we feature is ‘plastic’. (Actually: Polymethyl methacrylate Fluorinated Polymer, to be accurate.)
Being ‘plastic’ has advantages
The fibers are easier to work with in a hobby or star ceiling application as the are more “forgiving” when they are bent.
You’ll learn what John is doing in this photo, a bit later in the “FAQ’s”. But we can assure you that what he’s doing would NEVER work with GLASS fiber optic fibers!
