福州光骅达光电公司设计，加工，镀膜，提供各种规格C-lens透镜。 质量稳定，价格极具竞争力。客户包括国内外多家光通讯厂商。
C-lens产品特点
1. C-lens在材料上与普通透镜的不同，它采用了一种在光纤通信波段具有高折射率的材料，这种材料具有良好的耐酸碱腐蚀性，并且在C-lens两个端面镀增透膜的情况下，对光纤通信所用波段有着极高的透过率，可达99. 9% 以上。
2. 与传统的 G-lens相比，C-lens是一种折射率为常数的厚透镜，它的一个端面为球面，另一个端面为斜面。经理论计算，当其斜面倾角θ为8°时，C-lens光纤准直器的回波损耗值可大于 60dB，完全满足光纤通信的要求。
我司具有20年的Clens生产经验的专业厂家，提供定制或标准化C透镜产品。常规尺寸有：外径1.8*R1.419*2.98；外径1.0*1.2; 研磨角度，8°，5°等等。
除标准品外，各种规格可定制，任意曲率，任意角度，并提供高质量的镀膜服务。
C-lensisspecially designed for fiber optics usage in collimator, isolator,switch, collimator array and laser Assembly. Compared to othergradient index lens, C-lens has many advantages including low cost,low insertion loss in long working distance, wide working distancerange. With Photonchina experienced optical design Engineers, wealso provide the designing of c-lens according to customer'sre, beside our standard products list below.
