Graded index liquid crystal lens with carbon nanotube spacer

The invention relates to a graded index liquid crystal lens with a carbon nanotube spacer. There is provided an optical element including: a first optical substrate; a second optical substrate covering at least a portion of the first optical substrate; a liquid crystal layer disposed in a cell gap between the first optical substrate and the second optical substrate; and a plurality of carbon nanotube pillars, the plurality of carbon nanotube pillars extending across the cell gap between the first optical substrate and the second optical substrate. The carbon nanotube columns may have an aspect ratio of at least about 2: 1, and the carbon nanotube columns may be configured to maintain a uniform cell gap thickness. 本发明涉及具有碳纳米管隔离物的渐变折射率液晶透镜。提供一种光学元件，该光学元件包括：第一光学衬底；第二光学衬底，该第二光学衬底覆盖该第一光学衬底的至少一部分；液晶层，该液晶层设置在该第一光学衬底与该第二光学衬底之间的单元间隙内；以及多个碳纳米管柱，该多个碳纳米管柱在该第一光学衬底与该第二光学衬底之间跨该单元间隙延伸。碳纳米管柱的长径比可以至少约为2:1，并且碳纳米管柱可以被配置成维持均匀的单元间隙厚度。
