Scanning Particle Lens Array Laser Micro/Nano Patterning System

大自然已经成功地演示了使用表面纹理来增强功能。当使用传统的机械工具、聚焦离子束、电子束、化学蚀刻和光刻方法时，在人造材料上生产和复制这些复杂的纹理一直很困难。激光表面纹理具有复制此类图案的灵活性(适用于平面和曲面结构)和速度。然而，由于光学衍射的限制，在纳米级的生产中出现了挑战。Lig Nanowise(LIG)已经设计出一种有效的技术，可以在大面积上进行激光纳米加工，从而克服了这些挑战。它是基于自组装粒子透镜阵列在与角度入射激光相互作用的表面上的近场聚焦效应。

Nature has successfully demonstrated the use of surface textures to enhance functionality. The production and replication of these complex textures on man-made materials have been difficult when using conventional mechanical tooling, focused ion beams, electron beams, chemical etching and lithographic methods. Laser surface texturing has the flexibility (suitable for flat and curved structures) and speed to replicate such patterns. Howeverchallenges arise with the production is at nm scale due to the optical diffraction limit. LIG Nanowise (LIG) have devised an efficient technique for laser nanopatterning across a large surface area, which overcomes these challenges. It is based upon the near-field focussing effect of a self-assembled particle-lens array (PLA) on a surface interacting with an angularincident laser beam.
