Abstract: We present the test results of science grade substrate-removed 4Kx4K HgCdTe H4RG-15 NIR 1.7 mu m and SWIR 2.5 mu m sensor chip assemblies (SCAs). Teledyne’s 4Kx4K, 15 mu m pixel pitch infrared array, which was developed for the era of Extremely Large Telescopes, is first being used in new instrumentation on existing telescopes. We report the data on H4RG-15 arrays that have achieved science grade performance: very low dark current (<0.01 e(-)/pixel/sec), high quantum efficiency (70-90%), single CDS readout noise of 18 e(-), operability >97%, total crosstalk <1.5%, well capacity >70 ke(-), and power dissipation less than 4 mW. These SCAs are substrate-removed HgCdTe which simultaneously detect visible and infrared light, enabling spectrographs to use a single SCA for Visible-IR sensitivity. Larger focal plane arrays can be constructed by assembling mosaics of individual arrays.
