sapphire ball Dia 1.0 1.1 1.5 for optical ball lens high hardness single crystal
Key Feature
Single Crystal Sapphire Construction:
Manufactured from single crystal sapphire, these ball lenses provide superior mechanical strength and optical performance. The single-crystal structure eliminates defects, enhancing the lens's optical properties and durability.
High Hardness:
Sapphire is known for its extreme hardness with a Mohs hardness of 9, making it one of the hardest materials on earth, second only to diamond. This ensures that the lens surface remains scratch-resistant, even in the harshest environments.
Diameter Options:
The Sapphire Ball Lenses are available in three standard diameters: 1.0mm, 1.1mm, and 1.5mm, giving flexibility for different applications. Custom sizes are also available on request, allowing for tailored solutions based on specific optical design requirements.
Optical Transparency:
The lenses offer high optical transparency, making them suitable for a broad range of applications that require clear and unimpeded light transmission. The wide transmission range of 0.15-5.5μm ensures compatibility with both infrared and visible light wavelengths.
Surface Quality and Precision:
These lenses are polished to ensure a smooth surface with minimal roughness, typically around 0.1μm. This enhances the light transmission efficiency, reducing optical distortion and providing higher precision in optical systems.
Thermal and Chemical Resistance:
The single crystal sapphire ball lens features excellent thermal resistance with a high melting point of 2040°C and superior resistance to chemical corrosion, making it suitable for demanding environments, including high-temperature and chemically aggressive applications.
Custom Coatings Available:
To further enhance performance, the lenses can be coated with a variety of optical coatings such as anti-reflective coatings to improve transmission efficiency and minimize light loss.
