MATISSE是一个中红外光谱干涉仪，它结合了ESO VLTI多达四个望远镜的光束，使用LM和N波段的干涉光谱提供相位闭合和图像重建。本文介绍了用于低温准直的两个冷工作台的光机设计，该冷工作台包含几种类型的低温机构（快门、Tip/Pump）。关键方面进行了详细说明，如高度集成的光机械设计方法，以保证组件的稳定性和精度规格的纳米和弧秒的顺序。
MATISSE is a mid-infrared spectro-interferometer combining beams of up to four telescopes of the ESO VLTI providing phase closure and image reconstruction using interferometric spectra in the LM and N band. This paper presents the opto-mechanical design of the two cold benches containing several types of cryogenic mechanisms (shutter, Tip/Tilt) used for cryogenic alignment. Key aspects are detailed such as the highly integrated opto-mechanical approach of the design in order to guarantee component stability and accuracy specifications in the order of nanometers and arcseconds.
