光学性能:
可见光：可见光透过率较高 ：PMMA是目前最优良的高分子透明材料，可见光透过率达到92%，比玻璃的透光度高。
紫外光：石英能完全透过紫外线，但价格高昂，普通玻璃只能透过0.6%的紫外线，但PMMA却能透过73%。PMMA不能滤除紫外线（UV）。紫外光会穿透PMMA，部份制造商[2]在PMMA表面进行镀膜，以增加其滤除紫外光的效果和性质。另一方面，在照射紫外光的状况下，与聚碳酸酯相比，PMMA具有更佳的稳定性。
红外线：PMMA允许小于2800nm波长的红外线通过。更长波长的IR，小于25,000nm时，基本上可被阻挡。存在特殊的有色PMMA，可以让特定波长IR透过，同时阻挡可见光，（应用于远程控制或热感应等）。
