Product introduction:
Sapphire protective window is a product that utilizes the characteristics of sapphire such as pressure resistance, scratch resistance, and high temperature resistance to protect users or items in containers. It is often used in deep water, oil fields, flammable and explosive situations, high-pressure vessels, vacuum containers, and electronic sensors or external environment detectors
The laser protective window is mainly used to block debris from splashing during laser cutting and prevent splashes from damaging the lens. Anti-reflection coatings with high damage threshold (>15J/cm2) are plated on both sides to reduce reflections. It is currently widely used in light cutting, laser marking and other applications. Sapphire has the characteristics of high hardness (level 9), high temperature resistance (1600°C), and good thermal conductivity. It is increasingly replacing traditional quartz laser protection sheets.
The sapphire laser protective sheet is made of high-quality sapphire material, which can effectively avoid the phenomenon of explosion and abrasion caused by high temperature, and greatly improve the service life of the protection sheet.
