单支光纤 ：将多根光纤用胶或高温熔结集束，安装金属端头和外包装管，经端面抛光而成。

Single glass fiber
Bunching several glass fibers with rubber or high- temperature nodulizing，installment metal tips and outsourcing tabulating，and polishing side surfaces is the course of production.

双支硬管玻璃光纤

具有任意自锁定位特点，将光源发出光传送到任意区域，照明盲区可被抵制到最小。

 Double- hard -tube glass optical fiber
The product incorporates features of self-locking and localization，and it can transmit light from the illuminating source to anywhere so that illumination blind spot may be controlled to the smallest.

环型光纤

环型照明经过特殊设计与显微镜和CCD配套，它具有照明区域360º无隐阴阴影光斑均匀，使标本免于热辐射等特点广泛用于电子业的自动化照明、检测和仪器分析。

Annular glass optical fiber
Peculiarly designed and matched with CCD and microscope, the product incorporates features of providing non-shadow 360- degree illumination，protecting the specimen from heat emission . This contributes to its widely use in automatic illumination, detection and instrument analysis in the electronic cottage.
