Embodiment Construction
[0043] see figure 1 as well as figure 2 , figure 1 It is a flow chart of a manufacturing method of an optical module according to an embodiment of the present invention, figure 2 for matching figure 1 Schematic diagram of the process. First, step S10 is performed to provide a plate 1, wherein the plate 1 includes a lens structure 10 and a substrate 12, and the lens structure 10 is formed on a first surface 120 of the substrate 12, as figure 2 (A) shown. In this embodiment, the substrate 12 may be a glass substrate, but not limited thereto. Next, step S12 is executed, a groove 100 is cut on the lens structure 10 with a laser 2, and the first surface 120 of the substrate 12 is exposed in the groove 100, as figure 2 (B) with figure 2 (C) shown. Next, step S14 is performed, turning the board 1 over, and cutting a cutting line 124 on a second surface 122 of the substrate 12 with a cutter 3, wherein the second surface 122 is opposite to the first surface 120, and the cu...
