Environment-friendly optical glass and optical component

Abstract

The invention is intended to solve the technical problem of providing environment-friendly optical glass of high reflectivity and an optical component. The optical glass has reflectivity of 1.69-1.75and abbe number of 35-43. The optical glass comprises, by weight, 0.5-5% of Na2O, 3.89-10% of TiO2/(Na2O+K2O), 0.23-0.8% of TiO2/SiO2, 2.28-8% of TiO2/B2O3, and 25-43% of SiO2+B2O3, with Al2O3>SrO. The optical glass contains no environment-harmful components, such as PbO, As2O3 and fluorides, has good chemical stability, low crystallization temperature, low price and good melting performance. Theoptical glass is applicable to the devices, such as camera lenses, digital cameras, digital video cameras, and camera phones.

AI Technical Summary

Benefits of technology

This patented technology solves problems with current materials used on electronic devices like LCD screens by providing an improved protective window that doesn't include any potentially dangerous elements or compounds found therein. It also has excellent physical properties at high temperatures without losing its ability to transmit light effectively over long periods of time due to poor solubility caused by these ingredients.

Problems solved by technology

The technical problem addressed by these inventions relates to developing environmentally friendly materials for use with optics that are less prone to being harmful or damaging to human health when used at lower prices than traditional ones while still maintain their desired properties like excellent chemical stability (chemistry) and reduced crystal formation temperatures during manufacturing process.
