4. Kohærensforhindringsfilm ifølge krav 1, hvorved hældningsvinklen af i det mindste sideoverfladernes (24a) basisendedel er mindre end 88°.
5. Kohærensforhindringsfilm ifølge krav 1, hvorved en søjletæthed, som bestemmes som en procentdel af et enkelt fremsprings (24) basisareal (B) i forhold til et delt areal (Q), ikke er større end 2,5%.
6. Kohærensforhindringsfilm ifølge krav 1, hvorved fremspringet (24) har en keglestubformet form.
7. Berøringspanel vedhæftet kohærensforhindringsfilmen ifølge krav 1.
8. Berøringspanel ifølge krav 7, hvorved kohærensforhindringsfilmen (21) er vedhæftet en bagside heraf.
