| 摘要 |
An optical arrangement for pre-processing primary illumination light is proposed, wherein a provided spectral processing section (P) comprises a multi-prism assembly ( 10 ) consisting of a plurality of sequentially/consecutively connected prisms ( 21, 22 ). Pairs ( 20 ) of adjacent and connected prisms ( 21, 22 ) form a respective spectral separating face ( 20 c). The spectral separating face ( 20 c) is adapted in order to perform a process of spectral separation/splitting with respect to said primary illumination light (L 1 ).
