用熔成氧化硅玻璃或锗制成的折射微透镜阵列在可见光和近红外波段有良好的性能。透镜阵列的透镜间隙可以改变,直径为微米级,数值口径为f/2～f/20。这种透镜阵列有球面微透镜和柱面微透镜组成。美国亚利
Refractive microlens arrays made of fused silica or germanium have good properties in the visible and near infrared bands. Lens array lens gap can be changed, the diameter of microns, the numerical aperture f / 2 ~ f / 20. This lens array consists of a spherical microlens and a cylindrical microlens. American Yali
