●Coatings‌:
·Protective Layers‌: SiO₂ or Si₃N₄ coatings for environmental durability;
·High-LIDT Coatings‌: Compatible with ‌femtosecond‌ or ‌CO₂ laser (10.6μm)‌ systems‌.
3.‌Applications‌
●Laser Cavities‌: High-reflective mirrors for fiber/solid-state lasers;
●Space Optics‌: Lightweight mirrors for satellite sensors with radiation resistance;
●Spectroscopy‌: Beam splitters in FTIR or Raman systems‌.
4.‌Customization‌
●Complex Surfaces‌: Flat, spherical (‌R10–5000mm‌), or aspheric (parabolic, hyperbolic);
●Custom Shapes‌: Circular, square, annular, or client-defined with tailored edges;
●Fast Turnaround‌: Standard orders in ‌10 days‌, special requests ‌<4 weeks‌‌.
