Abstract

Unique concave microlens arrays (MLAs) made of calcite single crystals with tunable crystal orientations can be readily fabricated by template-assisted epitaxial growth in solution without additives under ambient conditions. While the non-birefringent calcite (001) MLA showed excellent imaging performance like brittlestar's microlens arrays, the birefringent calcite (104) MLA exhibited remarkable polarization-dependent optical properties.

摘要

独特的凹面微透镜阵列（MLAs）由方解石单晶体组成，晶体取向可调，可通过在无添加剂的情况下，在室温条件下，在溶液中进行模板辅助外延生长来制备。非双折射方解石（001）MLA 具有类似于海胆微透镜阵列的优异成像性能，而双折射方解石（104）MLA 则表现出显著的偏振相关光学特性。
