Features

High-Quality Material:

Made from optical-grade single crystal sapphire (Al2O3), our ball lenses provide excellent transmission properties and robustness. Sapphire's high hardness and scratch resistance ensure the lenses maintain optical clarity over time, even in harsh conditions.

Transmission Range:

These lenses are designed to operate effectively in a transmission range of 0.15-5.5μm, making them suitable for both infrared (IR) and visible light applications. This wide transmission range makes them versatile for a variety of optical systems, including sensors, lasers, and imaging devices.

Diameter and Customization:

Our sapphire ball lenses are available in standard 1mm and 1.5mm diameters, with the possibility for custom sizes depending on the specific needs of your application. The diameter tolerance is ±0.02mm, ensuring high precision for every lens.

Surface Quality:

The surface roughness is maintained at 0.1μm, ensuring a smooth finish that minimizes light scattering and maximizes transmission efficiency. Optional coatings (such as 80/50, 60/40, 40/20, or 20/10 S/D) can be applied based on customer requirements, optimizing lens performance for specific optical needs.

Durability and Strength:

Sapphire is one of the hardest known materials, with a Mohs hardness of 9. This makes our sapphire ball lenses highly resistant to scratching, ensuring they retain their clarity and functionality over extended use. Additionally, sapphire's high melting point of 2040°C makes these lenses suitable for high-temperature applications.

Custom Coating:

We offer customizable coatings to enhance the lens's optical performance, such as anti-reflective coatings and protective coatings to prevent damage from environmental factors.
