福州光骅达光电公司提供各种规格C-lens透镜。 质量稳定,价格具备竞争力。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,并提供高质量的镀膜服务。
C-lens is specially designed for fiber optics usage in collimator, isolator, switch, collimator array and laser Assembly. Compared to other gradient index lens, C-lens has many advantages including low cost, low insertion loss in long working distance, wide working distance range. With Photonchina experienced optical design Engineers, we also provide the designing of c-lens according to customer's requirements, beside our standard products list below.
