Simplifies manufacturing and maintenance processes.
Robust Construction:
High mechanical strength and chemical inertia.
Resistant to weld spatter, fumes, smoke, and debris in industrial environments.
Optical Performance:
Low absorption and scattering losses.
Maintains high IR reflectance (>98%@10.6μm) for efficient laser operation.
Ease of Maintenance:
Exceptionally scratch-resistant.
Can be cleaned with brushes and organic solvents without degradation.
Applications: CO2 Laser Systems, Industrial Laser Processing, Scientific and Research Applications, Medical Applications, etc.
