摘要:

在$γ$ -射线切伦科夫天文框架反射镜涂层在定义望远镜的光响应中起着至关重要的作用。我们使用数值模拟软件和真空室进行了新的镜面镀膜解决方案的研究,以进行小样品生产。在这篇文章中,我们提出了一种新的反射镜涂层解决方案,包括28层的干涉SiO $_{2}$ -TiO $_{2}$ -HfO $_{2}$设计沉积在玻璃基板上,其平均反射率是以上$90\%$垂直入射光的波长范围在300和550 nm之间。

英文摘要:

In the $γ$-ray Cherenkov Astronomy framework mirror coating plays a crucial role in defining the light response of the telescope. We carried out a study for new mirror coating solutions with both a numerical simulation software and a vacuum chamber for small sample production. In this article, we present a new mirror coating solution consisting of a 28-layer interferometric SiO$_{2}$-TiO$_{2}$-HfO$_{2}$ design deposited on a glass substrate, whose average reflectance is above $90\%$ for normally incident light in the wavelength range between 300 and 550 nm.
