1. Optical Performance
- Broad Spectral Transmission: >90% transmission in the ultraviolet (170–2500 nm) and infrared (up to 3500 nm) ranges, optimized for UV-Vis-NIR applications .
- Low Stray Light: Achieves λ/10 surface flatness (tested via Zygo interferometry) and Ra <1 nm (atomic force microscopy), minimizing light scattering and distortion.
2. Thermal Robustness
- High-Temperature Endurance: Operates continuously at 1100°C and withstands thermal shock (1100°C → room temperature without cracking) .
- Ultra-Low CTE: Thermal expansion coefficient of 0.55×10⁻⁶/°C (25–300°C), ensuring dimensional stability in extreme thermal cycling.
3. Mechanical & Chemical Durability
- Hardness & Strength: Mohs hardness of 7 and compressive strength of 1100 MPa, resistant to mechanical abrasion and high-pressure environments .
- Chemical Resistance: Impervious to acids (except HF) and organic solvents, validated in semiconductor wet etching and chemical vapor deposition (CVD) processes .
4. Surface Quality
- Ultra-Polished Finish: Surface roughness <1 nm (Ra) and 40/20 scratch/dig specification, critical for high-resolution imaging and laser optics .
1. Laser Systems
· Laser Output Windows: Serve as protective interfaces for CO₂ lasers (10.6 μm) and ultrafast lasers (femtosecond pulses), mitigating thermal lensing and beam distortion.
· UV Laser Shielding: Protect sensitive components in lithography and micromachining systems from UV-induced degradation.
2. Semiconductor Manufacturing
· Plasma Observation Windows: Enable real-time monitoring of plasma etching processes in wafer fabrication, maintaining vacuum integrity and optical clarity.
· CVD Chamber Viewports: Monitor thin-film deposition uniformity while resisting corrosive byproducts (e.g., SiCl₄, NF₃).
3. Vacuum & High-Radiation Environments
· Synchrotron Beamline Windows: Transmit hard X-rays (up to 35 keV) with minimal absorption in particle accelerators and free-electron lasers .
· Vacuum System Monitoring: Provide visibility into high-vacuum chambers without compromising pressure integrity.
4. Analytical Instrumentation
· Spectrometer Sample Windows: Ensure flat spectral response for Raman, FTIR, and UV-Vis spectroscopy, supporting material characterization.
· XRD Sample Holders: Maintain crystallographic alignment during diffraction analysis.
5. Defense & Aerospace
· Hypersonic Vehicle Windows: Withstand thermal gradients exceeding 1000°C/s and radiation doses >10⁶ rad.
· Laser Weapon Systems: Protect optical train components from high-energy laser pulses (100 kW–1 MW).
