Optical element, and assembly and optical system therewith

Abstract

An optical element for incorporation into a holding device for forming an assembly for constructing an optical system comprises a body transparent to light from a used wavelength range, on which a first light passage surface and an opposing second light passage surface are formed. Each light passage surface has an optical used region for arrangement in a used beam path of the optical system and an edge region outside the optical used region and designated as an engagement region for holding elements of the holding device. Each light passage surface is of optical quality in the optical used region and has a surface shape designed in accordance with a used region specification specified by the function of the optical element in the used beam path. Light deflection structures with a geometrically defined surface design are in the edge region of at least one of the light passage surfaces.
