The gel rod, partially polymerized CR-39 [diethylene glycol-bis-(allyl carbonate)], is placed in the atmosphere of trifluoroethyl methacrylate (3FMA) vapor, followed by heat-treatment to yield the GRIN rod. Examining the relationship between the preparation conditions and the optical properties of the GRIN rod, the plastic GRIN rods with a quadratic-index distribution up to their periphery and with higher than 0.36 N.A. were fabricated.
将部分聚合的CR-39[二甘醇双（烯丙基碳酸酯）]凝胶棒置于甲基丙烯酸三氟乙酯（3FMA）蒸汽气氛中，然后进行热处理以制备渐变折射率棒。通过研究制备条件与渐变折射率棒光学性能之间的关系，制造出了周边具有二次折射率分布且数值孔径高于0.36的塑料渐变折射率棒。
