Abrasion resistant antireflection coating for plastics

摘要

Coating of plastics for optical applications is mostly intended to improve their mechanically durability and to provide a desired optical function. A potential layer system to realize an antireflection function and to improve the mechanical properties simultaneously is a combinatio of hard coating SiO_2 with classical 4-layer antireflection system consisting of SiO_2 and Ta_2O_5. Plasma-Ion Assisted Deposition (Plasma-IAD) at room temperature has been applied for coating experiments on PMMA and Polycarbonate.
