Purple optical glass composition

Abstract

The invention provides a purple optical glass composition, comprising a base glass ingredient and a purple coloring agent, wherein the base glass comprises the following components by weight percent: 81% of SiO2, 2% of Al2O3, 4% of CaO, 4g of MgO, 5% of B2O3, 2% of BaO and 2% of TiO2; the purple coloring agent comprises the following components in parts by weight: 40-50 parts of MnO2, 20-30 parts of CoO and 20-30 parts of Co2O3; the weight percent of the base glass ingredient in the composition is 99.5% and the weight percent of the purple coloring agent is 0.5%. By reasonably adjusting the formula of the purple optical glass composition, the chemical stability of the glass is improved, and the purple optical glass composition is even in coloring, good in crystallization ability and high in refractive index.

AI Technical Summary

Benefits of technology

This technology helps improve the chemistry of soda-lime lamps without losing their effectiveness over time due to changes made during use or storage caused by factors like temperature fluctuations that can affect its performance. By doing this with specific formulas for each type of lamp, it becomes more stable than before they were used again after being stored at different temperatures.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the quality of coloured optics by ensuring consistently high levels of evenness with good crystal formation capabilities while maintaining their desired properties such as transmitting visible lights at different colors.
