Paper Title:
Effect of Aspect Ratio of Micro Sphere Lens Arrays on the Optical Property of Diffuser
  Abstract

The effect of the aspect ratio of micro sphere lens arrays on the optical properties of diffuser including transmittance and haze have been simulated by the LightTools software, and the results show that with the increasing of the aspect ratio, the haze rises first and drops later while the transmittance decreases all the time. Later, the mold with uniform micro sphere lens arrays arranged in regular triangle has been fabricated successfully by the ball embossing method. Then, the micro sphere lens arrays diffuser with aspect ratio of 0.19, 0.23, 0.26 and 0.29 have been made using the hot embossing method in polypropylene (PP) substrate. Last, haze and transmittance of the micro sphere lens arrays PP diffuser made are verified both by experiment and simulation and the results of experiment and simulation are consistent well.
