The Wide Field Camera (WFC) is an EUV telescope designed and built by the United Kingdom. The WFC has its own 0.525 m focal-length mirror assembly consisting of 3 nested Wolter-Schwarzschild mirrors (co-aligned with the XRT). The focal plane instrumentation consists of a curved microchannel plate (MCP) a carousel containing 8 filters, of which 6 are science filters. The WFC provides a 5 degree field-of-view with spatial resolution 2.3 arcmin HEW. Use of the various filters allows crude spectral resolution.
