Abstract: A dispersive element is disclosed which is designed to receive incident light (1) and disperse the incident light (1) into multiple spatially separated wavelengths of light. The dispersive body (DB) comprises a collimation cavity (COLL) to collimate the incident light (1), at least two optical interfaces (PRIS) to receive and disperse the collimated light (2) and a collection cavity (CLCT) to collect the dispersed light (3) from the at least two dispersive interfaces (op1, op2) and to focus the collected light (4).

Abstract: An optical sensor arrangement comprises an optical barrier which is placed between a light-emitting device and a photodetector. Herein the light-emitting device and the photodetector are arranged on a first plane and are covered by a cover. The photodetector exhibits an active zone. The optical barrier exhibits an extent along a first principal axis, which is pointing parallel to the line connecting the centers of the light-emitting device and the photodetector. Herein the extent is greater than a dimension of the active zone. The optical barrier is designed to block light emitted by the light-emitting device that otherwise would be reflected by the cover by means of specular reflection and would reach the photodetector. The optical barrier is designed to pass light emitted by the light-emitting device and scattered on or above an outer surface of the cover.
