Embodiment Construction

[0043] Figure 1A Shown is the first step of the method of printing a three-dimensional lens structure, ie providing a mold 1 with a surface area 2 defined in the shape of a well. In step B, pieces of printing material 3 are deposited on the mold and cured to build the three-dimensional lens structure 4 as shown in step C. The three-dimensional lens structure 4 shown here comprises a convex shape and a flat side opposite the convex shape.

[0044] Figure 2A Shown is the first step of the method of printing a three-dimensional lens structure, ie providing a mold 1 with a surface area 2 defined in the shape of a well. In step B, an intermediate layer 6 of eg a liquid UV-curable or thermosetting polymer is applied to ensure a perfect fit with the subsequently deposited segments of the printing process. In step C, fragments of the printing material 3 are deposited on the intermediate layer 6 present in the mold 1 and cured to build the three-dimensional lens structure 5 as show...

Abstract

The method relates to a method of printing a three-dimensional lenticular structure (5), comprising the steps of depositing segments of a printing material (3) on a substrate (1), and the step of curing the deposited segments to build said three-dimensional lenticular structure , wherein the substrate comprises a mold having a surface area (2) defined in a well shape.

Description

technical field [0001] The invention relates to a method of manufacturing a lens structure. Background technique [0002] There are various methods of fabricating lens structures. One well known method is molding of UV curable and thermoset polymers. Precise optical surfaces can be combined with thin layers (membranes, optical coatings, filters, etc.) depending on the molding technique. In addition, a plurality of lenses having different refractive indices can be stacked. The disadvantage of molding techniques is that shrinkage occurs during curing, making it difficult to control shape deformation and warpage, especially at heights >500 microns and combined with bulky mechanical features in the same material. Another method of manufacturing lens structures is injection molding. Injection molding enables greater freedom in combining optomechanical features, but the tooling is expensive, takes a long time to produce and does not allow the integration of heterogonous mat...
