Zusammenfassung: | A cassette includes a light transmissive window through which a temporally and spatially modulated image is passed. The window has a bottom surface, as part of the cassette, or as a separate component which may be separately interchangeable in the apparatus, or a part of the apparatus. In some embodiments: (i) the window bottom surface comprises a convex surface or consists essentially of a convex surface (e.g., without additional optical structure associated therewith); (ii) the window bottom surface comprises a concave surface or consists essentially of a concave surface (e.g., without additional optical structure associated therewith); (iii) the window bottom surface has a diffraction grating or Fresnel lens thereon or operatively associated therewith; (iv) a combination of (i) and (iii); or (v) a combination of (ii) and (iii). |
