Abstract

본 발명은 광학부품의 다층반사 방지막에 관한 것으로서, 고굴절률 광학부품의 경우에도 3층의 박막구조로 가시광선 영역에서의 분광투과율 향상을 꾀함과 아울러 통상의 광학적 박막 두께 제어방식으로도 쉽게 박막 두께를 제어할 수 있도록 하는데 그 목적이 있다. 이에 따라 가시광선의 기준파장을 λ0라 할때 유기기판(1)쪽으로부터 막두께 구성을 0.50λ0±0.05λ0인 제1층막과, 0.50λ0±0.05λ0인 제2층막 및 0.50λ0±0.05λ0인 제3층막으로 한 다층반사 방지막이 순차적으로 설치되고, 상기 제1층막의 물질은 Al2O3으로 하고, 상기 제2층막의 물질을 ZrO2와 Tio2의 혼합물질층으로 하고, 상기 제3층막의 물질을 MgF2로 하며, 이때 상기 기판의 굴절률(n)은 1.75에서 1.85범위 내에서 형성되도록하는 구성에 특징이 있다.
