Patent ID: 7310059

Claim:
A pane for a combat vehicle or vessel which is transparent to radiation used for a purpose of its own, comprising a first layer on an outer face of said pane with which the pane is adapted to reflect a major part of a first electromagnetic radiation emitted by an enemy, and to reduce the pane's emittance of a second electromagnetic radiation received by the enemy, and a second layer arranged on the first layer, said second layer absorbing said second radiation so as to increase the pane's emittance of the second radiation, a thickness of said second layer being chosen to increase said emittance of the second electromagnetic radiation to such an extent that a difference in intensity between the second electromagnetic radiation received by the enemy from the pane and the intensity received by said enemy from the parts of the combat vessel which adjoin the pane, is so small that the pane essentially cannot be distinguished in an image of the combat vessel generated from said second electromagnetic radiation, said second layer at the same time essentially maintaining the pane's capability of reflecting the first radiation.
