Posted on 2025-07-02, in Blog

In our recent market research, we found that some customers are unclear about Asahi's custom optical lens process. This article will explain in detail "What is the process for custom LED lens manufacturing?", including the information we need from you and the timeline for design and production.

Why Choose Custom LED Lenses?

We know that standard-mold lenses are widely available in the market, accounting for over 70% of the share.

However, with the evolution of the LED lighting industry and the growing demand for unique applications, off-the-shelf products can no longer fully meet specialized needs. This makes custom optical lenses increasingly important—and also puts greater demands on the technical expertise and manufacturing capabilities of lens producers.
