Abstract
(EN)
The documents show an optical beam splitter assembly (100) for recording images in at least three different spectral portions (110, 120, 130), comprising a first and a second beam splitter (151, 152), and a first, second and third light path (171, 172, 173), the first light path (171) being configured to guide light of a first spectral portion (110) from a light entrance section (160) to a first light output section (161), the second light path (172) being configured to guide light of a second spectral portion (120) from the light entrance section (160) to a second light output section (162), the second light output section (162) being spaced apart from the first light output section (161), and the third light path (173) being configured to guide light of a third spectral portion (130) from the light entrance section (160) to a third light output section (163), the third light output section (163) being spaced apart from the first light output section (161) and the second light output section (162), wherein the second light path (172) traverses the first beam splitter (151), and the third light path (173) traverses the first and the second beam splitter (151, 152).
