Float Borosilicate3.3 Glass
High-borosilicate3.3 thermal-shock-resistant float flat glass is a versatile material. The source states that China is the third country able to produce float high-borosilicate3.3 glass. Produced by the float process from sodium oxide (Na₂O),boron oxide (B₂O₃) and silicon dioxide (SiO₂),it is identified in the source as "plat borosilicate glass3.3" and as a substitute for SCHOTT borofloat®3.3 and CORNING pyrex®7740. The source lists boron content at12.5–13.5% and silicon content at78–80%. It is a Pyrex-type borosilicate glass with low thermal expansion and good thermal,chemical,optical-transmission and electrical properties. Its chemical-corrosion resistance,thermal-shock resistance,mechanical performance,high-temperature capability and hardness lead to its use as heat-resistant,thermal-shock-resistant,high-temperature and specialty fire-resistant glass.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
