Spectral analysis system for capturing a spectrum

Spectral analysis system for capturing a spectrum, comprising

• an inlet opening, a dispersive optical element and an at least partly reflective imaging or beam forming optics comprising at least one optical functional element defining an optical path from the inlet opening across the dispersive optical element onto an outlet opening and/or detector area of the spectral analysis system, wherein the dispersive optical element is configured in a movable manner;
• and
• a carrier member defining a flat optical path volume comprising at least one lateral opening,
• wherein at least one of
• the inlet opening,
• the outlet opening and/or detector area,
• the at least one optical functional element and
• the dispersive optical element
• is integrated in at least one member,
• wherein the at least one member is mounted on the carrier member at the at least one lateral opening, such that the optical path mainly runs transversely to a thickness direction of the optical path volume.
