Abstract

Dual-band cold mirrors are designed based on third-order of 121.6 nm multilayers, and they are only composed of LaF and MgF. The designed mirrors have a high reflectance at 121.6 nm and 280 nm, and a low reflectance in visible waveband; they also have a narrow bandwidth of 4 nm at 121.6 nm, and low sidelobe ripples of two stopbands. A broadband antireflection coating and an asymmetrically Gaussian-apodization of thickness-modulated design method are proposed to eliminate sidelobe ripples of the reflection zone.

摘要

双波段冷镜基于121.6纳米多层膜的三阶设计，仅由氟化镧和氟化镁组成。所设计的镜子在121.6纳米和280纳米处具有高反射率，在可见光波段具有低反射率；在121.6纳米处还具有4纳米的窄带宽以及两个阻带的低旁瓣纹波。提出了一种宽带减反射涂层和厚度调制设计方法的非对称高斯切趾来消除反射区的旁瓣纹波。
