title = "Concept design of the AMT front-end optics",
abstract = "The Africa Millimetre Telescope (AMT) is a project to realize the first millimeter-wave telescope in Namibia desert to participate in the Event Horizon Telescope (EHT) network and make higher-resolution pictures of black holes possible. We made a preliminary design of the optics to combine the beams of the first light receivers that will enable simultaneous observations of the same area of the sky in four frequency bands. The system is based on the use of dichroics and it has been designed following a geometrical optics approximation to guarantee that all beams will follow the same optical path.",
