The power of a light microscope is limited by the wavelength of visible light, which is about 500 nm.

光学显微镜的放大倍数受限于可见光的波长，大约500纳米。

For example, if pure white light hits an apple, all colors (wavelengths of light) are absorbed except for red (700-630 nm).

举例来说，纯粹的白光照射苹果，除红色外(波长700 - 630纳米)所有的颜色(所有波长)的光都会被吸收。

Based on plenty of experiment data and analyzing results, we made several one-dimensional photonic crystals used in visible light and near infrared light which have band gaps from ten to a hundred nm.

根据大量的实验数据和分析结果，我们镀制出可见光区和近红外区的一维光子晶体，禁带分别有几十到一百纳米。

Zech (The ADVENT Group of Colorado Springs, CO) noted optical storage technology expert, a new commercial optical storage technology using UV light would probably have to be in the 200 nm range and would provide storage capacities of over 100 GB in a single layer.
