Abstract

The invention describes a heating system (13) for heating a body (1) of a preform having a material thickness bounded by a first surface (2) and a second surface (4). The heating system (13) comprises at least a light source arrangement (12) which is arranged to emit a number of directed light beams (17) and a coupling arrangement (15, 21) realized to deliberately couple light from the light source arrangement (12) in a specific direction into the body (1) during at least a certain minimum period such that the light is essentially guided along a longer path (19) between the first (2) and second surface (4). Furthermore, the invention concerns a method of heating a body (1) of a preform.
