ABSTRACT:
The present invention relates to a simulator arranged for simulating firing and intended to be mounted on a weapon. The simulator includes an emitter for a simulation beam arranged to emit an electromagnetic beam, and beam shaping means located in the beam path of the simulation beam and arranged to shape the beam so that its beam lobe exhibits a predetermined shape within a large range of distances from a given minimum distance (Rmin) from the simulator principally out to a maximum range (Rmax) for the simulation beam. The invention is characterized in that the beam shaping means comprise an optical component having at least one diffractive transmitting surface, diffractive reflecting surface, aspherical refractive surface or aspherical reflective surface.
