Abstract: An optical switch (14) is provided that switches between a wash mode and a beam mode. A set of two parallel lenticular lenses (16, 18) with the same focal length are separated by a first distance (24) and are configured to adopt a beam configuration and a wash configuration. In the beam configuration, the parallel lenticular lenses are aligned along an identical axis such that the optical power of the set of lenticular lenses is approximately zero. In the wash configuration, one of the two parallel lenticular lenses is rotated with respect to the other parallel lenticular lenses.
