2090870 9200550 PCTABS00010 The invention relates to the optical colour filter with changeable colour can be applied expediently as adapter for optical pickup and projecting apparatuses, wherein layers are arranged influencing the intensity-rate of the components of various wave lengths of the rays of light between the two light-passing barrier layers, resp. the invention relates furthermore to the method for producing such optical colour filter, on the course of which layers are arranged between the two light-passing barrier layers, influencing the intensity-rate of the components of various wave lengths of the rays of light. In the sense of the invention the layer (4) between the barrier layers (2, 5) is made of large molecule foil, while on the course of the method for producing the optical filter adapter, the layer (4) to be placed between the barrier layers (2, 5) is manufactured from various large molecule foil or foils resulting dehomogenized molecule structure.
