    摘要: The invention provides a projection system (100) comprising a projection light source (110) and a color wheel (120), wherein the projection light source (110) comprises a solid state light source (115), configured to generate a solid state light source beam (111) having a solid state light source beam cross-section. Upstream of the color wheel (120) beam shaping optics (161) are arranged, configured to shape the solid state light source beam cross-section into a rectangular cross-section. The color wheel (120) comprises regions (125) of different luminescent material (170), excitable by the solid state light source beam (111) and configured to generate, upon excitation by the solid state light source beam (111), visible light (116) for projection on an image panel (290). The regions (125) are arranged at different distances from an axis of rotation (122) of the color wheel (120).

    摘要: In a method for evaluating the polarization state of an illumination system (52) in an optical system (50), a mask (56) is provided in the optical system (50) such that an illumination beam incident on the mask (56) is adapted such as to substantially differently diffract incident components of a light beam having different polarization states. An image of the mask (56) is then obtained, using an illumination beam of the illumination system (52) of the optical system (50). The obtained image, being either an intensity plot or a structure created in a resist layer by exposing the resist layer with the image of the mask (56), is then used to extract polarization related information about the illumination system (52). The image used for evaluating may be a diffraction image of the mask.
