Product Description
Sapphire Custom-Shaped Windows Optical Glass Multi-Form Customization Transmittance >85%
The sapphire custom-shaped window is a non-standard optical component precision-engineered from single-crystal aluminum oxide (α-Al₂O₃), specifically designed for specialized optical systems. Unlike conventional circular or square windows, it can be customized into complex geometries (polygonal, annular, D-shaped, etc.) while retaining sapphire's intrinsic properties - ultra-high hardness (Mohs 9) and broad-spectrum transmittance (250-5500nm). This unique design flexibility makes it an ideal solution for space-constrained, specialized optical path, or non-standard interface requirements, extensively applied in high-end laser systems, military electro-optics, and precision instrumentation.
Key Characteristics
· Complex Geometry Adaptability: Supports CNC-machined irregular contours (hexagonal, trapezoidal, sector-shaped, etc.) with edge tolerance controlled within ±0.02mm, ensuring perfect compatibility with non-standard optical chambers or device interfaces.
· Extreme Environmental Stability: Inherits sapphire's superior properties, withstanding high temperatures (800°C continuous/1800°C short-term), resisting acid/alkali corrosion (pH1-13), and maintaining optical stability under intense impact or particle erosion.
· Exceptional Optical Performance: Achieves >85% transmittance from UV to mid-IR, with optional anti-reflective coatings (<0.5% reflectivity at specific wavelengths like 1064nm/10.6μm) to minimize laser system energy loss.
· Outstanding Mechanical Strength: Flexural strength >600MPa allows processing ultra-thin structures (down to 0.2mm) without fracture, suitable for miniaturized optical modules.

Primary Applications
1. Special Laser Optical Systems: Serves as side-pump windows for fiber lasers or protective windows for ultrafast laser deflectors, precisely adapting to complex optical paths.
2. Defense & Aerospace: Used in missile seeker irregular radomes and asymmetric observation windows for airborne EO pods, balancing aerodynamic profiles with impact resistance.
3. Semiconductor Equipment: Functions as shaped viewports for etching machines and thin-film deposition systems, resisting plasma corrosion while providing distortion-free observation.
4. Medical & Scientific Instruments: Optimizes space utilization and optical efficiency in endoscopic articulating lenses and synchrotron radiation beamline deflectors.
FAQ
1. Q: What are the key advantages of sapphire windows over standard optical glass?
A: Sapphire windows offer 10x higher scratch resistance (Mohs 9), broader UV-IR transmission (250-5500nm), and superior thermal/chemical durability compared to optical glass.
2. Q: Can sapphire windows be customized for specific laser wavelengths?
A: Yes, we provide wavelength-specific AR coatings (e.g., 1064nm/10.6μm) with <0.5% reflectivity and λ/10 surface accuracy for laser applications.
