Clean Spaces
KASI OATG operates two clean booths and a clean room for fabrication, measurement and test of instruments and optical systems. Two clean booths are located in the electro-optical laboratory of Jangyoungsil Hall of the KASI. The OATG successfully done for early-phase fabrication and test of IGRINS at those clean booths.

Tower
The cleanroom at the Bitmarum Dong has a tower for optical performance measurement. The tower's height is 5 meters and it has a motorized mounting plate which can tilt and lift. we can install testing object (e.g. mirror) into the mounting plate and lift/rotate it to set the suitable distance and angle from measurement equipment.
