1. As an optical-grade product, LED lenses have strict requirements on light transmittance, thermal stability, density, refractive index uniformity, refractive index stability, water absorption, turbidity, and maximum long-term working temperature. Therefore, the lens material must be selected according to actual conditions.
  2. It must be equipped with a dust-free workshop with a level of 10,000 or higher.Operators must wear anti-static clothing, finger cots, and masks, and other anti-static and dust-proof measures, and regularly inspect and clean the workshop.
3. Product inspection: no bubbles, no depressions, no sink marks, no flow lines, no crescent;
4. The product must be anti-static and dust-proof and must be completely sealed. The temperature and humidity must be strictly controlled for storage, and it is best not to store it for more than one year.
