光学透镜表面的反射会改变其光学特性。为了克服这个问题，使用抗反射结构（ARS）来防止反射。先前研究中使用的树脂对于光学器件来说并不令人满意，因此在本研究中，使用新开发的树脂来制造具有防污性能的光学透镜。实验结果表明，与未制备的光学透镜相比，制备的光学透镜具有较高的水接触角和较低的滑落角的防污性能。还发现，在擦拭测试中，即使擦拭25次，镜片的形状和反射率也没有变化。此外，峰值1/e2全宽的测量结果表明，所制造的透镜和非ARS透镜表现出相似的光学性能。
Reflectance on an optical lens surface changes its optical characteristics. To overcome this problem, an antireflection structure (ARS) was used to prevent reflection. The resin used in previous studies was not satisfactory for the optical device, and therefore in this study, a newly developed resin was used to fabricate an optical lens with antifouling property. Experimental results showed that the fabricated optical lens exhibited an antifouling property with a higher water contact angle and a lower slip drop angle compared to those of the non-fabricated optical lens. It was also found that there was no change in the shape and reflectance of the lens even after wiping 25 times in a wiping test. Furthermore, the result of the measurement the full width at 1/e2 of peak indicated that the fabricated lens and the non-ARS lens showed similar optical performance.
