SOXS是新技术望远镜(NTT)的新型光谱仪，针对瞬变和可变物体进行了优化，覆盖了从350到2000 nm的宽波长范围。SOXS配备了一个校准单元，进一步提供作者信息：(将信件发送到H.K.，电子邮件：hanun@utu.fi)ar X iv：2 01 2.12 68 5v 1[as tr oph I.M]2 3D EC 2 02 0，将用于删除仪器签名并为数据提供波长校准。校准组将使用七个校准灯：一个用于平场校正的石英钨卤素和一个重气灯，一个用于波长校正的塔尔灯和四个铅笔式稀有气体灯。通过使用积分球和定制的双光束，来自校准灯的光被注入模拟NTT的f/11输入光束的光谱仪。超大的照明贴片均匀覆盖了光谱仪狭缝的长度，变化幅度为1%。该光学系统还支持该单元的第二种模式，即利用针孔掩模模拟点源的星形模拟器模式。在直接照明模式和针孔模式之间的切换是由线性阶段执行的。当灯箱盖被移除时，安全联锁关闭主电源，防止维修人员意外暴露在紫外线下。所有电源和控制模块都放置在一个电子机架中，与望远镜平台保持一定距离。在本报告中，我们描述了SOXS校准单元的光学、机械和电气设计，并报告了该单元目前处于测试和验证阶段的开发状况。

The calibration unit will employ seven calibration lamps: a quartz-tungsten-halogen and a deuterium lamp for the flat-field correction, a ThAr lamp and four pencil-style rare-gas lamps for the wavelength calibration. The light from the calibration lamps is injected into the spectrograph mimicking the f/11 input beam of the NTT, by using an integrating sphere and a custom doublet. The oversized illumination patch covers the length of the spectrograph slit homogeneously, with < 1% variation. The optics also supports the second mode of the unit, the star-simulator mode that emulates a point source by utilizing a pinhole mask. Switching between the direct illumination and pinhole modes is performed by a linear stage. A safety interlock switches off the main power when the lamp box cover is removed, preventing accidental UV exposure to the service personnel. All power supplies and control modules are located in an electronic rack at a distance from the telescope platform. In this presentation we describe the optical, mechanical, and electrical designs of the SOXS calibration unit, and report the status of development in which the unit is currently in the test and verification stage.
