The CoRoT optical design minimized stray light coming from the Earth and provided a field of view of 2.7° by 3.05°.
The CoRoT optical path consisted of a 27 cm (10.6 in) diameter off-axis afocal telescope housed in a two-stage opaque baffle specifically designed to block sunlight reflected by the Earth and a camera consisting of a dioptric objective and a focal box.
Inside the focal box was an array of four CCD detectors protected against radiation by aluminum shielding 10mm thick.
The asteroseismology CCDs are defocused by 760μm toward the dioptric objective to avoid saturation of the brightest stars.
A prism in front of the planet detection CCDs gives a small spectrum designed to disperse more strongly in the blue wavelengths.

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 13.5 μm × 13.5 μm in size which corresponds to an angular pixel size of 2.32 arcsec.
 The CCDs are cooled to −40 °C (233.2 K; −40.0 °F).
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°.

The satellite, built in the Cannes Mandelieu Space Center, had a launch mass of 630 kg, was 4.10 m long, 1.984 m in diameter and was powered by two solar panels.
