Apparatus, comprising:Means for the light beam division (500) for parts of an incident light beam in three separate light beams, each with a first, second and third wavelength, which are parallel to one another;a 3 - channel - modulator (700) for modulating the beams of light, which, via the means for the light beam division (500) were divided, in accordance with a picture signal which is input from an external source; andan agent for the light beam combination (800) to form a combined light beam by a combination of the three light beams with the first, second and third wavelength of the 3 - channel - modulator (700) were modulated,characterized in thatthe image a light path compensator (600) which is adapted, to ensure that the focal points of all three of the means for the light beam division (500) light beams emitted on the same point of its respective channel in the 3 - channel - modulator (700) lie;the means for the light beam division (500) as a hybrid light beam is formed in the direction of pitch;the means for the light beam combination (800) as a hybrid light beam combination before the direction is formed; andthe hybrid beam division before direction, the..
