Testing the CHEOPS scientific instrument

Testing the CHEOPS scientific instrument

The CHEOPS scientific instrument is pictured here being loaded into the thermal vacuum chamber at the University of Bern, for testing.

The instrument consists of a photometer with a single CCD, operating between 0.4 µm and 1.05 µm, that is at the focal plane of an on-axis Ritchey-Chrétien telescope of 33 cm diameter.

In the picture, the telescope tube points towards a window in the chamber through which light can be offered during testing. Light entering the telescope is detected by the bronze-coloured Focal Plane Module (FPM), which houses the CCD detector array and the Front-End Electronics.

These tests are carried out to ensure that the alignment of the FPM performed in ambient conditions results in correctly focussed images once in orbit.
