Abstract利用国内首个自上向下热蒸发反射膜的大型镀膜机ZZS3200,开展了2.4m望远镜铝反射镜镀介质保护膜的研究。根据2.4m望远镜主镜面型,结合ZZS3200型镀膜机真空室空间几何配置,分析了介质保护膜膜厚均匀性,设计了一款自上向下热蒸发保护膜材料的蒸发舟,开展了铝反射镜的介质保护膜工艺研究。结果表明:蒸发舟蒸发特性接近1,2.4m主镜介质保护膜膜厚不均匀性小于13.6%。脱膜清洗效果表明,相比于SiO2保护膜,MgF2保护膜更容易清洗,可减少脱膜对镜面造成的腐蚀,并有更高的反射率,更适合于2.4m望远镜主镜。完成2.4m望远镜主镜镀铝加MgF2保护膜,陪镀片在350~1100nm波段范围内,平均反射率为87.16%,实测2.4m望远镜极限星等不低于23.5等。
