Product Description

Sapphire Circular Window Sapphire Glass 90% Transmittance For Laser Window

ZMSH manufacture precision sapphire circular windows (5-300mm diameter, 0.3-20mm thick) with >85% transmittance (250-5500nm) and Mohs 9 hardness for demanding optical applications. Our comprehensive capabilities include custom AR coatings (R<0.5% per surface), precision edge treatments (beveled/safety edges), and metrology-grade surface finishes (up to λ/10 flatness). Utilizing advanced CNC machining and laser processing technologies, we achieve tight tolerances of ±0.01mm while maintaining excellent thermal stability (CTE 5.3×10⁻⁶/℃) and chemical resistance. We serve laser systems, semiconductor equipment and aerospace instrumentation markets with reliable 2-4 week lead times for custom solutions. Additional services include multi-aperture drilling, laser marking, and cleanroom packaging upon request.

Key Characteristics

1. Superior Optical Performance: The sapphire circular window achieves over 85% transmittance from 250nm to 5500nm wavelengths, with particularly outstanding performance in the 3-5μm MIR range, making it suitable for infrared thermal imaging and laser transmission applications.

2. Exceptional Mechanical Strength: With a Mohs hardness of 9, its scratch resistance is 10× greater than standard optical glass, capable of withstanding high-velocity particle impact and repeated friction.

3. Extreme Environmental Resistance: Featuring a melting point of 2040°C, it maintains stable operation at 800°C continuously (short-term tolerance up to 1800°C) while demonstrating excellent acid/alkali resistance (stable in pH 1-13 environments), suitable for chemical and marine applications.

4. Stable Thermodynamic Properties: Its low thermal expansion coefficient (5.3×10⁻⁶/°C) matches various metals and ceramics, preserving optical surface accuracy (<λ/4 @632.8nm) under rapid thermal cycling.

Primary Applications

1. Laser Optical Systems: Serving as output windows and protective lenses for CO₂ and fiber lasers, sapphire circular windows withstand high-power laser irradiation (>5kW/cm²) while minimizing thermal lensing effects.

2. High-Temperature Industrial Observation: Used as viewports in steelmaking and glass-forming equipment, maintaining optical clarity above 1000°C without the fogging or deformation issues of conventional glass.

3. Aerospace and Defense: Employed as protective windows for aircraft electro-optical sensors and missile seekers, combining lightweight properties (density 3.98g/cm³) with impact resistance against supersonic aerodynamic heating.

4. Scientific Instruments and Medical Devices: Providing biocompatible surfaces and stable optical channels for synchrotron radiation equipment and endoscopes.


FAQ

1. Q: What are the advantages of sapphire windows over glass?
A: Sapphire offers 10x higher scratch resistance (Mohs 9), wider spectral transmission (UV to IR), and superior thermal/chemical durability.

2. Q: Can sapphire windows be customized for laser applications?
A: Yes, we provide laser-grade sapphire with AR coatings (<0.5% reflectivity) and λ/10 surface finishes for high-power systems.
