Process for the manufacture of glass with a high transmission characteristic in the visible spectral range and a high reflection behavior for heat radiation, and lenses made by the process.
MANUFACTURING PROCESS OF HIGH PERFORMANCE DISK DRIVE IN THE SPECTRUM VISIBLE AND HIGH PERFORMANCE FOR REFLECTION radiant heat as well as low surface resistance. MINERAL GLASS substrates GOES RIDING A layer system in the following order: LAYER1: OXIDE GROUP stannic oxide, silicon dioxide, aluminum oxide, tantalum oxide and zirconium oxide or oxides MIXTURES. Layer 2: ALLOY 80% by weight of nickel and 20% by weight of chromium. CAPA3: silver or a silver alloy with a silver content of 50% WEIGHT minimum. CAPA4: ALLOY 80% by weight of nickel and 20% by weight of chromium. CAPA5: OXIDE GROUP stannic oxide, silicon oxide, aluminum oxide, tantalum oxide and zirconium oxide or oxides MIXTURES. Then heats the substrate YET SET LAYER TO Softening CRYSTAL AND PERMANENTLY TO GIVE YOU THE DUAL.
