Ever thought: a 520 megapixel camera...!!

Yes! This not so familiar looking optical instrument is actually a camera, named DECam after its primary application.

It will be used to explore the presence of dark energy in our universe in new ways.

To achieve its scientific goals, there are plans to conduct a ground-based experiment that includes building the Dark Energy Camera ( or DECam) and installing it on the Blanco Telescope on Cerro Tololo in Chile.

For this, there are plans to build DECam, a digital camera with 520 megapixels, at Fermilab, using charged-coupled devices (CCDs).
