Automotive optics

Aspherical lenses used in automotive dipped headlights and fog lamps are made of glass of own production. Performance — 30 thousand lenses per month. The quality and precision requirements of mechanically treated lenses are significantly higher than those obtained by hot pressing, which guarantees high lighting performance for modern lighting systems.
