Liger is a next generation adaptive optics (AO) fed integral field spectrograph (IFS) and imager for the W. M. Keck Observatory. This new instrument is being designed to take advantage of the upgraded AO system provided by Keck All-Sky Precision Adaptive-optics (KAPA). Liger will provide higher spectral resolving power (R∼4,00010,000), wider wavelength coverage (∼0.8-2.4 μm), and larger fields of view than any current IFS. We present the design and analysis for a custom-made dewar chamber for…
