Tapered Optical Fiber / Custom-made(TOF)

Tapered optical fibers use optical fibers shaped with a large input diameter and small output diameter, to deliver a spot size that cannot be achieved by focusing with a lens. Optical fibers are constructed by melting and stretching them using heaters or torches, and can be made into any desired fiber diameter to suit requests. (*The core/cladding ratio is fixed, so the outer diameter differs on the input side and output side)
