And the optical components, if you look at the inset up on the right, we had to figure out a way to manufacture lenses in paper itself at really high throughputs, so it uses a process of self-assembly and surface tension to build achromatic lenses in the paper itself.
光学部分，如果你看右边插图， 我们必须得想一个办法 可以以纸本身为材料， 高效率地生产透镜。 通过自行组装 以及表面张力， 就可以在纸里面造出消色差透镜了。
