The stack (100) has two spacer parts (106, 108) material-conclusively attached to two layers (102, 104), respectively. The spacer parts have a groove (110) and a spring (112) for interlinking the spacer parts in a stacking direction of the stack to produce connection between the spacer parts and to produce spacing between the layers in a stack direction. The layers have an optical component (114) that is selected from a group consisting of lenses, prisms, diffractive structures, holografical structures and optical filters. An optically used area is defined by an area between the layers. An independent claim is also included for a method for manufacturing an optical layer stack. |
