WFI: Wide Field Imager
HOME INDEX SEARCH HELP NEWS
General
spacer The Wide Field Imager (WFI) is a focal reducer-type camera which is permanently mounted at the Cassegrain focus of the 2.2-m MPG/ESO telescope at La Silla. With field of view of 34'x33', Nyquist sampled by 0.238'' pixels exceeding any other ESO instrument by a factor of 2. It offers excellent sensitivity from 350 nm to the near IR, with more than 40 filters simultaneously available, many of them specifically selected to support the determination of photometric redshifts of distant objects.

Instrument scientists: Blair Conn & Oliver Schuetz
