Abstract
The invention concerns a device whereby micro-optic parts, particularly those that tend to tilt because of their geometric dimensions, can be precisely arranged on a support. The device according to the invention comprises a support (TR) on which several guide elements (FE1 . . . FE4) are placed in cutouts (A1 l . . . A4). The arrangement of the guide elements (FE1 . . . FE4) is such that the micro-optic part (BT) to be positioned can be inserted between the guide elements (FE1 . . . FE4). In this way an active adjustment is not required. In a particularly advantageous embodiment of the invention, the guide elements (FE1 . . . FE4) touch the micro-optic part (BT) at points that are located at different distances from the surface of the support (TR). In this way tilting is prevented in a particularly effective manner. The support (TR) is made of a silicon substrate for example; the guide elements (FE1 . . . FE4) can be uncoated spherical lenses which are placed in cutouts etched into the substrate by means of wet chemical methods.
