Raytrix
Raytrix GmbH is a German company founded by Christian Perwass and Lennart Wietzke that was the first to create and market commercial plenoptic cameras. The R5 camera produces images of 1 megapixel resolution, while the R11 produces 3 megapixel images. Unlike Lytro, which focuses on the consumer market, the main market of Raytrix's cameras is industrial and scientific applications where depth-information of each pixel can be useful.
