A device for the directed transmission of the radiation energy emitted from a radiation source is described, which is arranged between the energy source and the region to be heated. The device has a honeycombed lattice structure, the matrix of which has open-ended cells which are arranged lying opposite one another about the tyransmission axis. The individual cells have reflecting inner walls and have an orthogonal cross-section in planes relative to the axes of the cells which extend in the axial direction of the structure. These axes run at an angle in relation to the transmission axis so that a focal point of the structure is present on one side of the transmission axis. The lengths of the cells are different along the relevant axes thereof and are relative to the cross-sectional areas thereof so that, when the radiation source is arranged in the focal point, the radiated energy is not reflected more than twice on the inner walls of the cells, and is reflected from the outer peripheral walls of the cells in the direction of the other side of the structure along lines which run parallel to the transmission axis.
