光通信用自聚焦透镜的制备
Preparation of a self-focusing lens for optical communication
【摘要】 制备了自聚焦透镜的基础玻璃 ,对其透过率进行了测试 ,并对由这种玻璃制成的梯度折射率(GRIN)棒的折射率分布进行了分析。结果表明 ,基础玻璃在可见和近红外波段的透过率大于 89%;GRIN棒内部的折射率分布接近理想分布。
【Abstract】 The base glass for a self-focusing lens was prepared. The test on its optical transmittance was conducted, and analysis of the refractive index profile of a gradient index (GRIN) rod made of the base glass was performed. The results show the current base glass possesses transmittance higher than 89% in visible and near infrared bands, and the refractive index profile in the GRIN rod is in close proximity to the ideal distribution.
