  • The Effects of Profile Errors of Microlens Surfaces on

    Microlens arrays (MLAs) are key optical components in laser beam homogenization. However, due to imperfect surface profiles resulting from microfabriion, the functionalities of MLAs in beam modulation could be compromised to some extent. In order to address this issue, the effects of surface profile mismatches between ideal and fabried MLAs on beam homogenization were analyzed.
