Abstract
An article and method for manufacturing an optical reading head (400,500) including an optically transparent substrate (100) with a first surface (103) and a second surface (116), wherein the first surface (103) and the second surface (116) are joined at an angle. Depositing a plurality of layers having an upper portion (114), a middle portion (111, 112, 113), and a lower portion (101) that are optically active on the first and second surfaces (103, 116) of the optically transparent substrate (100). Forming light emitting devices (406, 407) in the plurality of layers on the second surface (116), thereby generating light emitting devices (406, 407) on the angle in the plurality of layers of the second surface (116). Positioning a detection device (402) in a normal plane to the first surface (103).
