2025年1月14日 · The Wide-Field Instrument (WFI), the primary instrument aboard NASA's Nancy Grace Roman Space Telescope, is a 300-megapixel visible and infrared camera that will allow scientists to perform revolutionary astrophysics surveys.

2025年1月15日 · The Wide Field Instrument (WFI) is a 300-megapixel infrared camera that will allow scientists to explore the cosmos all the way from the outskirts of our solar system to the edge of the observable universe.

2019年6月26日 · The Nancy Grace Roman Space Telescope is a next-generation space telescope that will survey the infrared universe from beyond the orbit of the Moon. The spacecraft's giant camera, the Wide Field Instrument (WFI), will be fundamental to this exploration. The WFI features the same angular resolution as Hubble but with 100 times the field of …

2024年6月3日 · The Roman WFI slitless grism has a spectral range of 1.00-1.93 microns and a dispersion of about 1.1 nm/pixel, essentially independent of wavelength, yielding a 2-pixel resolving power of R = λ / δλ = 460 λ / μm for a point source.

Roman's Wide Field Instrument (WFI) is a 300-megapixel infrared camera that will allow scientists to explore the cosmos all the way from the edge of our solar system to the farthest reaches of space.

2020年1月5日 · WFIRST will capture the equivalent of 100 high-resolution Hubble images in a single shot, imaging large areas of the sky 1,000 times faster than Hubble. In several months, WFIRST could survey as much of the sky in near-infrared light — in just as much detail — as Hubble has over its entire three decades.

2024年11月5日 · The Roman WFI detector focal plane consists of 18 H4RG-10 detectors in a 6 x 3 array that combined provide an 0.281 deg2 active FOV. This image shows the focal plane Engineering Test Unit with non-flight candidate detectors. The Wide-Field Instrument (WFI) is the primary instrument of the Roman Space Telescope

2022年8月19日 · Detectors that passed flight acceptance testing exceed performance requirements and program exceeded requirement on detector yield. WFI flight hardware is solidly in the build and test phase and heading toward full instrument integration and test in 2023!
