Fiber optics
In the Fitz lab, we used the following fibers for LED stimulation:
BFH48-200, BFH48-400 (from Thor Labs)
To cut these fibers:
use a lighter to burn off the clading (coating)
insert the fiber into a fiber cleaver such as the CL-60
score the fiber with the blade in the cleaver
bend the fiber to make a clean break at the scored point
