Abstract: The invention relates to a device for transmission of incoming radiation comprising a plate of a transparent material provided with a first flat side and a second side opposed to the first side, the second side being provided with a prismatic structure with certain magic apex angle which has a first and a second angle, wherein the apex angle of the prismatic structure is equal to a magic apex angle. The device can be applied advantageously in greenhouses and solar collectors to maintain a substantially constant transmission of incoming radiation from the sun during a long period of the day. To adjust the level of the limited transmission between a minimum transmission of 50% and the Fresnel transmission the prismatic structure can be provided with flat portions between the prisms.
