摘要
SOXS是新型技术望远镜（NTT）的一台新光谱仪，针对暂现与变源优化，覆盖350至2000 nm的宽波长范围。SOXS配备一个定标单元，用于消除仪器特征并为数据提供波长定标。该定标单元将采用七盏定标灯：一盏石英-钨-卤素灯和一盏氘灯用于平场校正，一盏ThAr灯和四盏笔式稀有气体灯用于波长定标。通过使用积分球与定制双合透镜，定标灯的光被注入光谱仪，模拟NTT的f/11输入光束。超大尺寸的照明光斑均匀覆盖光谱狭缝长度，变化小于。该光学系统也支持单元的第二模式，即利用针孔掩模模拟点源的星模拟器模式。直接照明与针孔模式之间的切换由直线模组完成。当灯箱盖被移除时，安全互锁会切断主电源，防止服务人员意外暴露于紫外线下。所有电源与控制模块位于远离望远镜平台的电子机柜中。在本报告中，我们描述了SOXS定标单元的光学、机械与电气设计，并报告该单元当前处于测试与验证阶段的开发状态。
