An optical system ( 10 ) operatively associated with incident light ( 50 ) is provided. The incident light is essentially comprised of a first part ( 52 ) and a second part ( 54 ). The optical system includes: a photo catalytic reactor ( 30 ) comprising a photo catalyst ( 36 ) operatively associated with the first part of the incident light, an optical device ( 20 ) operatively associated with the second part of the incident light, and a beam splitter ( 40 ) for separating the incident light into the first part which is directed to the photo catalyst and the second part which is directed to the optical device.
