The focal plane of the Vera C. Rubin telescope consists of 189 4kx4k charge-coupled device (CCD) sensors, arranged in a total of 21 3-by-3 square arrays. The system is cooled to about -100 °C to minimize noise.
The 3.5° field of view of the 64 cm wide array is 40 times the area of the full moon in the sky.
