摘要

在需要以長工作距離以提高光程之應用情形下，常需要準直光束，故本論文是設計並製作具有準直光束之熔燒式光纖透鏡。本研究將探討如何分析製作熔燒式光纖透鏡、漸變折射率式光纖透鏡及點膠式光纖透鏡，並探討這三種光纖透鏡之差異及使用上之限制。在製作熔燒式光纖透鏡會因為電弧放電則透鏡有偏心的情況發生，目前可控制的曲率半徑是經由電流改變來控制，範圍為70~125μm，誤差約±2μm。漸變折射率式光纖透鏡僅需要做精密的切割即可完成，在切割長度可控制在100μm~10mm，由於切割儀器精準度為10μm，所以會有±12μm的誤差量。點膠式光纖透鏡透過電漿來處理表面即可控制曲率半徑，目前可控制的曲率半徑為65~92μm，誤差約±2μm。

In order to improve the situation of application of heightening light in the long distance, the collimation light beam was always needed. The topic of this study was designing and making arcing fiber lens with collimation light beam. In this thesis, the main idea was how to analyze and make acing、gradient index and UV-curable fiber tens, and investigate the differences and restriction of usages between these three kinds of fiber lens. Lens will discharge due to the tilting are during the making of arcing fiber lens. So far, this situation can be controlled by having the curvature radius range between 70~125μm ±2μm. This can be completed by cutting the gradient index fiber lens with precise measurements. The range of cutting length was 100μm~10mm. As the result of the 10μm of distributing points limit, the margin of error will be ±12μm. The surface of UV-curable fiber lens can be handled through O2 plasma. So far, the radius curvature can be controlled within the range of 65~92μm and margin of error will be ±2μm.
