Close-up photo of DECam

The DECam focal plane consists of a science array of sixty-two 2048 X 4096 CCDs. Additionally there are four 2048 X 2048 guider CCDs and eight 2048 X 2048 focus and alignment CCDs. The quantum efficiency of these LBNL-designed CCDs with their anti-reflective coating is red optimized to be > 90% at 900 nm and over 60% over the range of 400-1000 nm. The DES CCDs were fabricated by Dalsa with further processing done by LBNL. They were then packaged and tested by Fermilab.
