Description
I will give an overview of the Roman Space Telescope, with a focus on the 18 Teledyne H4RG-10 detectors of its flagship Wide Field Instrument. The science requirements for Roman-WFI are unprecedented in the level of calibration that they demand, from <0.1% knowledge of the observed point-spread function, to <0.4% nonlinearity over four orders of magnitude, to ultra-low persistence. I will summarize the importance of these requirements to Roman science and review the ongoing progress towards meeting them.
