Product Description
Ruby Optical Window with 85% Transmittance (DSP) for Laser Transmission Customized
The Ruby Optical Window is a premium optical component fabricated from synthetic ruby (Cr³⁺-doped α-Al₂O₃ single crystal), specifically engineered for optical systems operating under extreme conditions. Compared to conventional optical glass, ruby optical windows deliver superior mechanical strength and environmental durability while maintaining excellent light transmission properties, making them ideal protective windows for high-power laser systems, high-temperature industrial inspection equipment, and special environmental monitoring devices. These windows effectively shield internal precision optical components from dust, corrosive media, and mechanical impacts, ensuring long-term stable operation.
Key Characteristics
1. Broad-Spectrum High Transmittance: Ruby optical windows achieve >90% transmittance in the visible spectrum (400-700nm) and maintain >85% in the near-infrared range (700-1500nm), meeting the requirements of most laser and optical sensing systems.
2. Exceptional Mechanical Properties: With a Mohs hardness of 9, their scratch resistance is 20× greater than standard optical glass, effectively withstanding sand erosion and mechanical abrasion.
3. Outstanding Environmental Resistance: Capable of continuous operation at 1200°C (short-term tolerance up to 1500°C) while exhibiting excellent acid/alkali corrosion resistance (stable in pH 1-14 environments).
4. Superior Thermal Stability: The low thermal expansion coefficient (6.5×10⁻⁶/°C) maintains optical surface accuracy (<λ/8 @632.8nm) under rapid thermal cycling.
