One or more first illuminating means are arranged on the first side of the support and adapted to illuminate from a first side of a light transmissive optical component held by the support. One or more second illuminating means are arranged on a second side of the support and adapted to illuminate from a second side of the light transmissive optical component held by the support, the second side of the support opposing the first side of said support. One or more third illuminating means arranged on the second side of the support and adapted to provide transmissive illumination at the second side of the light transmissive optical component held by the support, the third illuminating means comprises one or more of an illuminating surface and a light blocking surface selectively operable
