Abstract为优化兴隆1m光学望远镜的杂散光效应,研制了附加在该望远镜F/8焦面后的“一倍放大率消杂散光镜头”,对消杂散光镜头的效果进行了仿真计算和观测验证。在Tracepro软件中对“圆顶-1m望远镜”和”圆顶-1m望远镜-消杂散光镜头”组合系统的“点源辐照度透过率(PSNIT)”进行了计算分析并在大月夜进行了天文观测。计算结果表明,在视场外无限远点源方位与望远镜指向间夹角5°≤|θ|≤30°使用消杂散光镜头后,该望远镜PSNIT全部降低到10^-10以下。2008年5月26日对偏月22°和25°天区观测结果表明,使用消杂散光镜头后,该望远镜所观测的星像信噪比约为原来的1.4倍。仿真计算和观测结果表明:该方法对Ritchey-Chretien(R-C)望远镜的杂散光抑制是有效的,可以提高望远镜的测光精度和观测极限星等。
