Product Description
Sapphire Square Window Optical Glass Wear-Resistant High Transmittance Customizable
The sapphire square window plate is a high-performance optical component crafted from single-crystal aluminum oxide (Al₂O₃), offering exceptional durability and optical clarity for demanding applications. Available in standard sizes ranging from 5×5mm to 200×200mm with thickness options of 0.3-15mm, these window plates can be customized to specific dimensional requirements including unique edge profiles and surface treatments. Our precision manufacturing capabilities include laser cutting and CNC machining to achieve tight tolerances, along with optical polishing to λ/10 surface flatness standards, while optional anti-reflective coatings (R<0.5% per surface) further enhance light transmission performance for specialized optical systems.
Key Characteristics
1. High Transmittance: The sapphire square window plate demonstrates excellent optical transmittance (>80%) across ultraviolet (UV) to infrared (IR) wavelengths (0.15-5.5μm), making it suitable for broadband spectral applications.
2. Exceptional Hardness & Wear Resistance: With a Mohs hardness of 9 (second only to diamond), it effectively resists sand erosion, particle impact, and mechanical abrasion, ensuring extended service life.
3. Extreme Environment Resistance: Capable of withstanding high temperatures (melting point 2040°C) and corrosive conditions (stable in acid/alkali environments), ideal for demanding aerospace and military applications.
4. Low Thermal Expansion Coefficient: Exhibits outstanding thermal stability, maintaining optical surface precision during rapid temperature fluctuations to prevent image distortion.

Primary Applications
1. Optoelectronic Equipment Windows: Used as protective windows for lasers and infrared thermal imagers, ensuring stable operation in dusty, humid, or high-temperature environments.
2. Aerospace & Military: Serves as missile radomes and observation windows for airborne electro-optical pods, combining lightweight properties with impact resistance.
3. Industrial Sensing & Inspection: Functions as corrosion-resistant viewports for semiconductor equipment and high-temperature industrial cameras, guaranteeing long-term reliability.
4. Scientific Research & Medical: Employed in high-energy laser experiments and endoscopes, providing high-purity surfaces and biocompatibility.
FAQ
1. Q: What are the advantages of sapphire square window plates compared to glass?
A: Sapphire offers 10x higher hardness (Mohs 9), 3x better thermal conductivity, and superior transmission from UV to IR wavelengths.
2. Q: Can sapphire windows withstand high-pressure environments?
A: Yes, with compressive strength >2GPa and fracture toughness of 2MPa·m¹/², they excel in high-pressure applications.
