Abstract
An optical separating filter separates impinging light into a first and a second part having different properties. The separating filter comprises reflective filters (FR) arranged in funnel shaped structures (F). Each one of the structures (F) have an inlet area (IA) to receive the impinging light (IL) and an outlet area (OA) smaller than the inlet area. (IA) to converge reflected impinging light (RL) towards the outlet area (OA). The structures (F) comprise a first group of funnel shaped structures (F) constructed to reflect light which has a first property (C) towards their respective first outlet areas (OA) and for transmitting light which has a second property (C) towards respective second outlet areas (OA).
