摘要
The manufacturing of at least one photothermal converter element according to the invention consists essentially of implanting a multiplicity of substantially uniformly distributed parallely projecting transparent fibers (4) onto a baseplate element (1) provided with an absorbing coating (2) of a normally solid material capable of being temporarily converted to a plastic state, thanks to the use of an array of guiding means (5, 6, 7) arranged above the paseplate element. The implantation proper of the desired fiber structure is then performed by advancing a series of bundles (10) of fibers (4) through the array of guiding means, to the desired level above the baseplate element, and by clipping the advanced bundles to the desired length above the guiding means (5, 6, 7), so as to cause the falling with limited transverse spreading of the clipped fibers onto the coating of the baseplate element. This coating being concurrently converted to its plastic state, the clipped fibers are then caused to adhere to the plastic coating, which is then solidified so as to firmly secure the adhering fibers. The array of guiding means (5, 6, 7) is finally withdrawn from the firmly secured fiber structure. The baseplate element thus provided with such a firmly secured fiber structure thereby constitutes a photothermal converter element.
