These lenses were specially developed for so called 3-CCD cameras. In this kind of camera the taken picture is divided into three separate images by a beam splitter. Each of these three images is then directed onto a individual CCD sensor with a filter for one of the basic colours red, green or blue.
The advantage of these 3-CCD cameras is the higher resolution for the recorded pictures. Due to the complex ways of light inside such cameras no standard lenses can be used.
