Limiting device for electromagnetic radiation, notably in an analysis device |
摘要 |
A limiting device (9) for electromagnetic radiation (3; 5; 7) includes an essentially flat beam cross-section limiter (10) which partly or completely encloses at least one passage aperture (12; 13) for beams (5; 7) and is constructed so that it also includes at least one second beam cross-section limiter (14) which, in the active position, constitutes at least one longitudinal component extending at an angle to the first beam cross-section limiter (10).
