Fused silica laser protective windows are designed to provide a high level of protection for both equipment and individuals in laser-based applications.
These windows are constructed from fused silica, a high-purity amorphous silicon dioxide material, known for its excellent optical properties, high thermal resistance, and low coefficient of thermal expansion. Fused silica offers exceptional transmittance across a wide range of wavelengths, making it ideal for various laser systems.
The windows act as a barrier, safeguarding operators and equipment from potentially harmful laser emissions by absorbing, reflecting, or diffusing the laser energy.
Features
Imported Quartz crystal material, uniform texture, high mechanical strength, high temperature and high-pressure resistance, and the lens is not easy to crack and collapse.
Excellent substrate is selected, which has excellent optical performance and good thermal stability. The lens manufactured by slicing, polishing, grinding and other high-precision processes is resistant to high temperatures and has strong laser performance.
-High Accuracy: High processing accuracy, no burrs, and fast cutting speed.
-Faster Cutting: Fast cutting speed, high surface finish, and long service life.
-Good Durability: High-quality raw materials can ensure the durability and stability of the product.
