    Abstract: An illumination system has a plurality (2) of light-collimating sections (12, 12', 12") and a light-mixing section (3). The light-collimating sections are arranged substantially parallel to each other along a longitudinal axis (25) of the illumination system. Each of the light-collimating sections is associated with at least one light emitter (R, G, B). Each of the light emitters is being in optical contact with the respective light-collimating section via a dielectric material with a refractive index larger than or equal to 1.3. At a side facing away from the light emitters, the light-collimating sections merge into the light­mixing, the light-collimating sections and the light-mixing section forming one integral part. Light propagation in the light-mixing section is based on total internal reflection and the light-mixing section has a plurality of faces parallel to the longitudinal axis. Preferably, the light-mixing section at a side facing away from the light emitters is provided with a further light-collimating section.

    Abstract: An optical device (1) for scanning three information layers (2, 2', 2") by means of three radiation beams (20, 20’, 20’’) having three respective wavelengths (λ 1 , λ 2 , λ 3 ) and polarizations (p 1 , p 2 , p 3 ), wherein the three wavelengths substantially differ from each other. The device comprises a radiation source (7) for emitting the three radiation beams, an objective lens system (8) for converging the three radiation beams beam on the positions of the three respective information layers, and a phase structure (24) having a non-periodic stepped profile. Furthermore, the structure includes birefringent material sensitive to the three polarizations and the stepped profile is designed for introducing three wavefront modifications (ΔW 1 , ΔW 2 , ΔW 3 ) for the three wavelengths, respectively, wherein one of the wavefront modifications is of a type different from the others and one of the polarizations differs from the others.

    Abstract: An optical head (1) for scanning an optical record carrier (2) is provided with a compensator (16) for compensating the field curvature aberration of the objective system (18) caused by operation of the optical head at a different field angles. A surface of the compensator (16) comprises a phase structure in the form of annular areas (52, 53, 54, 55, 56), the areas forming a non-periodic pattern of optical paths of different lengths. The optical paths change as a function of field angle and form a field angle-dependent wavefront deviation that compensates field curvature of the optical head.
