小孔内窥仪由内窥镜、照明光源、闭路电视、照相机及其他附件组成。其主要组成部份是内窥镜,内窥镜有三种:软内窥镜(即光学纤维内窥镜),硬内窥镜(即透镜组合内窥镜)和微型内窥镜(即自聚焦纤维内窥镜)。软内窥镜主要由光学纤维束构成,具有可弯曲的特点。光学纤维束,是一种能弯曲传光和传象的光学元件。近二十年,随着这种元件工艺的不断改善和以它为基础的各种新型光学 Endoscope hole by the endoscope, lighting, CCTV, cameras and other accessories. The main components are the endoscope, there are three kinds of endoscope: soft endoscope (ie optical fiber endoscope), hard endoscope (ie, lens combination endoscope) and micro-endoscope (ie, self-focusing Fiber endoscope). Soft endoscope is mainly composed of optical fiber bundles, with a flexible feature. Optical fiber bundle, is an optical element that can bend light and image. Nearly two decades, with the continuous improvement of this component technology and the various new optics based on it
