摘要： 选用MMA为单体M1、3FEA为单体M2,通过悬浮扩散共聚法制备了可见光透过率为90%的聚合物GRIN小球.采用剪切干涉法测得小球内的折射率基本上呈抛物线型球对称梯度分布,折射率差Δn达到0.019.

Abstract: A polymer spherical GRIN sphere lens was prepared by the suspension-diffusion-copolymerization(SDC) technique by using MMA as monomer M1 and 3FEA as M2. The radial distribution of refractive index of the lens was measured by the shearing interference method, which demonstrated that the quadratic refractive-index distribution was formed in the sphere lens, and its Δn=0.019.

Key words: Suspension-diffusion-copolymerization(SDC), Microsphere lens, Spherical symmetry gradient index distribution, Shearing interferometric technique
