The four CCD detectors are model 4280 CCDs provided by E2V Technologies. These CCDs are frame-transfer, thinned, back-illuminated designs in a 2,048 by 2,048 pixel array. Each pixel is in size which corresponds to an angular pixel size of 2.32 arcsec. The CCDs are cooled to . These detectors are arranged in a square pattern with two each dedicated to the planetary detection and asteroseismology. The data output stream from the CCDs are connected in two "chains". Each chain has one planetary detection CCD and one asteroseismology CCD. The field of view for planetary detection is 3.5°.
