Faint Object Camera

The camera was built by Dornier GmbH and was funded by the European Space Agency.

The unit actually consists of two complete and independent camera systems designed to provide extremely high resolution, exceeding 0.05 arcseconds.

It is designed to view very faint UV and optical light from 115 to 650 nanometers in wavelength.

[1] FOC has been compared to a "telephoto" lens, providing a high resolution in a small field of view.
