Alkali-free / Boro-aluminosilicate glass
High borosilicate glass (also known as hard glass) is made by utilizing the conductive properties of glass at high temperature, through heating inside the glass to realize glass melting, and processed by advanced production technology, because the linear thermal expansion coefficient is (3.3 ±0.1)×10-6/K, also known as "borosilicate glass 3.3".Silicon has a lower refractive index than germanium and has a lower density that makes for less weighty optical designs.
Alkali-free/boroaluminosilicate glass, also known as borosilicate glass, is a type of glass that is composed of a combination of boron oxide (B₂O₃), aluminum oxide (Al₂O₃), and silicon dioxide (SiO₂). It is referred to as "alkali-free" because it does not contain alkali metal oxides like sodium oxide (Na₂O) or potassium oxide (K₂O), which are commonly found in other types of glass.
