Abstract: An instrument cluster, in particular for a vehicle, has a dial with a plurality of graphic areas, which are backlit by a device provided with at least one light source, with a front light-guiding element having a front face at least partially covered by a back surface of the dial, and with a rear light-guiding element; the latter has a receiving portion facing said light source and a transmitting portion, which transmits and guides the light received by the receiving portion and is spaced apart from and faces a rear face of the front light-guiding element; the rear face of the front light-guiding element has an optical compensation system, having curved convex or curved concave lens surfaces, for varying the intensity of the light transmitted from said transmission portion to the different graphic areas.
