Abstract

The present invention relates to the technical field of lenses, and particularly relates to a film lens and a preparation process thereof. The film lens comprises a highly-transparent polyester film layer, and a highly-transparent polymer coating coated on the polyester film layer. The highly-transparent polymer coating is a curved-surface coating. The preparation process of the lens successively comprises the following steps of dedusting, removing an oxidation layer, applying the coating, curing, cutting and inspecting. The coating is coated on the film of the film lens, instead of the plastic injection production manner in the prior art. Therefore, the problems of stress marks, flow lines, bubbles and the like during plastic injection production process in the prior art can be solved. Meanwhile, the prepared film lens is high in abrasion resistance. The imaging distortion, the deformation and other defective phenomena of finished products are substantially eliminated.

Description

technical field [0001] The invention relates to the technical field of lens lenses, in particular to a film lens and a preparation process thereof. Background technique [0002] Most of the existing mobile phone and other lens production processes produce lenses through mold injection molding. This production method has the following defects: [0003] 1. Long production cycle, high production cost and low efficiency; [0004] 2. The lens has serious quality problems such as silver streaks, water inclusions, flow lines, air bubbles, and dissatisfaction with injection molding caused by the injection process; [0005] 3. The consistency of the product is not good, and the focus changes due to different injection molding processes; [0006] 4. The product is easy to deform and not strong in wear resistance. [0007] Therefore, it is urgent to develop a new lens to replace the existing technology. Contents of the invention [0008] In view of this, it is necessary to provid...
