Scanning Particle Lens Array Laser Micro/Nano-patterning System

大自然已经成功地展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是困难的。激光表面纹理具有灵活性（适用于平面和弯曲结构）和复制这些图案的速度。然而，由于光学衍射极限的限制，在纳米尺度上的生产带来了挑战。LIG Nanowise设计了一种有效的技术，可以在大表面积上进行激光纳米图案，克服了这些挑战。它是基于自组装粒子透镜阵列（PLA）在表面上与角度入射激光束相互作用的近场聚焦效应。

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. However challenges arise with the production is at nanometre scale due to the optical diffraction limit. LIG Nanowise has devised an efficient technique for laser nano-patterning 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 angular incident laser beam.
