<p>An arrangement in which the light emitted by a source of light (44) is directed by means of illumination optics (12) onto a surface (25) by which an image can be generated that can be projected by means of projection optics (4), onto a screen, wherein the illumination optics (12) have an optical device (28) arranged following the source of light and a prism (10) positioned between the surface (25) and the optical device (28), and the light coming from the optical device (28) is deflected without reflection by means of the prism (10) herein the optical device (28) has a first optical axis (29), and wherein said projection optics comprises a first and a second partial optics (22, 24) having a shared second optical axis (20) and in that the surface (25) is reflective, whereby the first optical axis (29), together with the second optical axis (20), includes an angle that is smaller than 90°, and whereby the optical device (28) lies outside of an area that is traversed from the second partial optics (24) to the first partial optics (22) by the light that is reflected off the surface (25.)</p> |
