TECS 39 Fiber
• Numerical aperture of 0.39 is available in two designs:
– Low-OH¯ fibers for visible to near-IR transmission
– High-OH¯ fibers for UV to visible transmission
TECS 48 Fiber
• High numerical aperture of 0.48:
– Couples over 50% more power than TECS 39 fiber
– Couples over 370% more power than standard silica-clad fibers
– Less critical fiber alignment requirements
– Reduced bending losses
