Colorless gradient-index cylindrical lenses with high numerical apertures in slabs 200-1000 µm thick have been fabricated by silver-sodium ion exchange in a specially developed glass. The lenses with numerical apertures of 0.6 are characterized by index profiles and by spherical and chromatic aberration. On-axis focusing properties and the application to the collimation of high-power laser diode bars are discussed.
通过在一种专门研制的玻璃中进行银钠离子交换，已制造出厚度为200 - 1000微米的无色渐变折射率圆柱透镜，其具有高数值孔径。数值孔径为0.6的透镜通过折射率分布以及球差和色差来表征。讨论了其轴上聚焦特性以及在高功率激光二极管棒准直中的应用。
