Abstract

본 발명은 광 콜리메이터에 관한 것으로서, 더 상세하게는 광 콜리메이터를 구성하는 광섬유의 단면을 비구면으로 함으로써 역반사(Backerflection)를 감소시키고 광 콜리메이터의 제조에 수반되는 여러공정을 단순화 시킨 광 콜리메이터에 관한 것이다. 이를 위한 본 발명은, 광섬유와 콜리메이터 렌즈를 구비하여 된 광 콜리메이터에 있어서, 상기 광섬유와 콜리메이터 렌즈는 소정거리 이격되어 있으며, 상기 광섬유의 단면은 비구면으로 되어 있는 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical collimator, and more particularly, to an optical collimator in which the cross-section of an optical fiber constituting a light collimator is made aspherical, thereby reducing back reflection and simplifying various processes involved in manufacturing an optical collimator . To this end, the present invention provides an optical collimator including an optical fiber and a collimator lens, wherein the optical fiber and the collimator lens are separated from each other by a predetermined distance, and the optical fiber has an aspheric cross section.

이로써, 본 발명 광 콜리메이터는 역반사를 효과적으로 감소시킬 수 있으며, 그 제조공정을 단순화시킴과 동시에 제조단가를 낮출 수 있는 이점을 제공한다.Thus, the optical collimator of the present invention can effectively reduce the retroreflectivity, simplify the manufacturing process, and reduce the manufacturing cost.
