Precise Prediction of Optical Performance for Near Infrared Instrument Using Adaptive Fitting Line

Infrared optical systems are operated at low temperature and vacuum (LT-V) condition, whereas the assembly and alignment are performed at room temperature and non-vacuum (RT-NV) condition. The differences in temperature and pressure between assembly/alignment environments and operation environment...

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-
