H2RG

The H2RG, also known as the Wide Field Infrared Camera 3 (WFC3) detector, is a scientific instrument used on the Hubble Space Telescope. It is a large format Charge-Coupled Device (CCD) that operates in the visible and near-infrared portions of the electromagnetic spectrum. The H2RG was developed by Teledyne Scientific and Imaging and was installed on Hubble during Servicing Mission 4 in May 2009.

Its primary function is to capture high-resolution images of celestial objects, enabling astronomers to study a wide range of phenomena. The camera's sensitivity across its operational wavelengths allows for observations of distant galaxies, star-forming regions, and exoplanet atmospheres. The H2RG is crucial for studying the early universe, the evolution of galaxies, and the properties of planets outside our solar system. It offers both imaging and spectroscopic capabilities, providing detailed information about the composition, temperature, and motion of astronomical sources. The data collected by the H2RG has led to numerous scientific discoveries and continues to be a vital resource for astrophysical research.
