Is it possible to couple a 200μm core fiber into a 50μm core fiber by using a 4x magnifier/reducer?
Fiber Optic Coupling -- how to couple a 200μm core fiber into a 50μm core fiber?
Click For Summary
SUMMARY
Coupling a 200μm core fiber into a 50μm core fiber is achievable using a 4x magnifier/reducer or a single lens with the formula ## \frac{m}{b}=\frac{1}{4} ##, where 'b' represents the object distance and 'm' the image distance. The primary challenge lies in the precise alignment of the focused beam onto the 50μm input, particularly in the z-direction. Successful implementation requires careful attention to these alignment details to ensure optimal coupling efficiency.
