| + | The pictures below all reveal a band of damage near the clamped end of the spooled light guide. This discovery is important: if a weak foam-lined clamp (chip-clip style) can cause this damage, then one must wonder about other potential mishandling. I have observed hook-and-loop ties used to store fiber bundles, fibers laid across tables, fibers laid over sandpaper (quickly moved when pointed out), and fibers rubbing against other fibers. I hypothesize that the sharp edges of the square guides are most prone to damage, but that all procedures for manipulating fibers are leaving marks. Pictures of the chip-clip and the hook-and-loop fasteners to come. |
