Abstract

An arrangement for the collection of light within a designated frequency interval, such as visible light, comprising a light- refracting lens (5) and a first light transporting or light- transforming organ (1), wherein the first organ shows a light entry (Ia) that is arranged at or in the proximity of the focal point of the lens for light within the designated frequency interval. The arrangement comprises a frequency selective mirror (4) that is arranged to enable transportation of incoming light within the designated frequency interval to the light entry and to resist transportation of incoming light outside the designated frequency interval to the light entry. The light entry is encased in a body (3, 7) whose outer surface is separated from the focal point of the lens for light within the designated frequency interval.
