1. As an optical-grade product, LED lens has extremely high requirements for light transmittance and water shrinkage. The raw material is generally high-grade optical-grade PMMA. Currently, Mitsubishi PMMA is the most commonly used (currently VH5 and VH001 materials are the best).

2. Must be equipped with 10,000-level or higher-level dust-free workshops. Operators must wear dust-free clothes and dust-free caps, take anti-static and dust-proof measures, and regularly inspect and clean the workshop;

From the above LED lens design and production process, the seemingly simple LED two-lens lens, from design to finished product, its software and hardware requirements are very high, which also causes the price of LED lenses on the market to vary greatly. From the perspective of the bright prospects of LED lighting, the lens as a complementary product of LED lighting, the prospects will also get better and better.
