Device for projecting a stereo color image

A device for projecting a stereo color image upon a screen (S) including

• a projection lamp (PL) for emission of a radiation spectrum,
• a beam splitter (ST2) for separation of the radiation spectrum emitted from the projection lamp into a first partial light bundle (D1, G1, R1) and a second partial light bundle (B2, G2, R2) complimentary to the first part light bundle (D1, G1, R1),
• first and second color image modulators (FM1, FM2), wherein said first color image modulator (FM1) produces a half image comprised of said first partial light bundle (B1, G1, R1) and said second image modulator (FM2) produces a half image comprised of said second partial light bundle (B2, G2, R2),
• a beam integrator (SV) provided subsequent to the color image modulators (FM1, FM2) for reuniting the first partial light bundle (D1, G1, R1) with the second partial light bundle (B2, G2, R2), and
• a lens system (Ob) for output of the therefrom resulting color image,
• wherein the beam splitter (ST2) includes a splitter dichroic mirror (D1) with triple band pass characteristic.
