    Abstract: Method for manufacturing an optical unit (1) comprising a plurality of glass-sheets (2) having an aspherical shape, arranged superimposed and spaced apart to form a stack (10), comprising the steps of: - arranging either a pre-bent or a flat glass-sheet (2) on a reference surface (5) having the geometry desired to be reproduced; - cold-deforming said glass-sheet (2) so as to adhere it onto the reference surface (5); - integrating said glass-sheet (2) with a preceding element (4, 2) of said stack (10) in a predetermined relative position; and - repeating the preceding steps till stack completion. The integration step comprises fastening said glass-sheet (2) in a position spaced from the preceding element (4, 12) of the stack (10) by means of bars (3) arranged spaced apart from one another.

    Abstract translation: 一种用于制造光学单元（1）的方法，包括多个玻璃板（2），该玻璃板（2）具有非球面形状，被重叠并间隔布置以形成叠层（10），包括以下步骤： - 将预弯曲或 在具有希望再现的几何形状的基准表面（5）上的平板玻璃板（2）; - 将所述玻璃板（2）冷变形以将其粘附到所述参考表面（5）上; - 将所述玻璃板（2）与所述堆叠（10）的先前元件（4,2）预定相对位置一体化; 和 - 重复前述步骤直到堆叠完成。 整合步骤包括通过彼此间隔布置的杆（3）将所述玻璃板（2）紧固在与所述堆叠（10）的先前元件（4,12）间隔开的位置。
