مصطلحات موضوعية: instrument: infrared spectrograph 1. INTRODUCTION Infrared optical systems are operated at low temperature and vacuum (LT-V) condition to minimize thermal noise. In general, the manufacture, assembly, and alignment of optical systems are performed at room temperature and non-vacuum (RT-NV) condition. If the temperature and pressure conditions alter, the physical changes of optical and opto-mechanical parts occur (Kaneda et al. 2005, Leviton et al. 2005), and this drives the optical performance variation. For visible light optical systems that are operated at RT-NV condition, the tasks of alignment and performance measurement after measurement are also performed at RT-NV condition, and thus the alignment process is intuitive (Kim et al. 2005, Liu et al. 2005, Kim et al. 2007, Kim et al. 2009). However, for infrared optical systems that are operated at LT-V condition, assembly is performed at RT-, wavefront error prediction and no adjustment philosophy, instrument: infrared spectrograph, Astronomy, QB1-991
