Abstract

Liger is an adaptive optics (AO)-fed imager and integral field spectrograph (IFS) designed for W.M. Keck Observatory. This paper will discuss the assembly, integration, and testing (AIT) of the Liger instrument. The project is currently in the first of two-fabrication phases where we are manufacturing, assembling, and testing the complete imager system, the IFS camera TMA, grating turret mechanism, and the IFS re-imaging optics mechanisms. The second fabrication phase will include the final fabrication and assembly of the IFS and science cryostat. An integration phase will follow where the full instrument is assembled and integrated into the science cryostat. Once complete the Liger will be shipped to Hawaii for final assembly, integration, and verification at W.M. Keck Observatory.
