光学元件;OPTICAL ELEMENT

摘要

一种光学元件，其包含设置在基材上且与该基材接触的抗反射层。该抗反射层具有大于1至小于1.41的折射率，并且具有大于0至小于300nm之范围的细孔大小。抗反射层包括最外表面，该最外表面具有如使用ASTM 5946-04所测定的大于或等于70°至小于或等于120°之范围的水接触角。 An optical element comprises an antireflective layer that is disposed on and in contact with a substrate. The antireflective layer has a refractive index of greater than 1 to less than 1.41 and has a pore size ranging from greater than 0 to less than 300 nm. The antireflective layer includes an outermost surface having a water contact angle ranging from greater than or equal to 70° to less than or equal to 120°
