摘要

我国将在南极建设2.5 m光学红外望远镜KDUST,为了解决镜面结霜问题,提出了氧化铟锡(ITO)薄膜加热的防霜方法。利用该方法,密封透射结构的南极巡天望远镜(AST)已经成功地应用于南极冰穹A。讨论了ITO薄膜集成于反射膜系用于防霜的可行性、防霜反射镜的制备工艺以及防霜反射镜在不同加热功率下的面形变化情况。实验结果表明,集成了ITO薄膜的反射镜具有防霜功能且对镜面面形的影响较小,有望应用于南极大型反射式望远镜系统中。

Abstract

The 2.5-m optical infrared telescope KDUST will be built in Antarctica by our country. In order to solve the problem of mirror frosting, the anti-frosting method by heating the indium tin oxide (ITO) film is proposed. With this method, the Antarctic Survey Telescope (AST) with sealed transmission structure has successfully been applied at the Antarctic Dome A. The anti-frosting feasibility of ITO thin films integrated in the reflecting film system, the preparation process and the surface shape variation of the anti-frosting reflector at different heating powers are discussed. The experimental results show that the ITO thin film integrated reflector has anti-frosting ability and little influence on the shape of the reflector surface, which can be applied to the large telescope system with reflection configuration in Antarctica.
