Sapphire Lens

ECOPTIK provides a comprehensive range of sapphire optical components, including sapphire lenses, sapphire windows, sapphire mirrors, sapphire cylindrical lenses, sapphire prisms, sapphire light guides, sapphire domes, and other customized sapphire optics.

Sapphire material is widely selected for demanding optical applications due to its outstanding mechanical strength, excellent chemical stability, high-temperature resistance, and broad spectral transmission capability. These properties make sapphire components suitable for optical systems operating under harsh environmental conditions and high-performance requirements.

Key Features

Exceptional Mechanical Strength

Sapphire is one of the hardest optical materials available, second only to diamond in hardness.

Its superior mechanical properties provide:

• High compressive strength

• Excellent scratch resistance

• Strong impact resistance

• Reliable performance in high-pressure and high-speed environments

These characteristics make sapphire optics suitable for applications requiring long service life and enhanced surface durability.

Excellent Chemical and Thermal Stability

Sapphire demonstrates outstanding resistance to chemical attack and environmental degradation.

Material advantages include:

• High resistance to strong acids and corrosive environments

• Low hydroxyl absorption characteristics around 1.4 μm, 2.2 μm, and 2.7 μm wavelengths

• Suitable performance for chemical analysis and spectroscopy applications

• High melting point up to 2053°C for extreme temperature environments

This stability allows sapphire components to maintain consistent optical performance under demanding operating conditions.

Superior Thermal Performance

Compared with fused silica, sapphire offers higher thermal conductivity, allowing faster heat dissipation during high-power optical operations.

The improved thermal management capability helps:

• Reduce temperature-related optical distortion

• Minimize thermal focus drift

• Improve stability in high-power laser systems

Sapphire is therefore suitable for applications where thermal control is critical.

Broad Spectral Transmission and High Refractive Index

Sapphire optical components provide a wide transmission range covering ultraviolet, visible, and mid-infrared wavelengths.

Key optical characteristics include:

• Transmission range approximately from 0.15 μm to 5.5 μm

• High refractive index of approximately 1.77

The higher refractive index enables more compact optical designs, allowing thinner and lighter lenses while maintaining the required focal length performance.

Applications

ECOPTIK sapphire optical components are widely used in:

• Laser systems

• Infrared optical equipment

• Chemical analysis instruments

• High-temperature optical systems

• Industrial imaging equipment

• Precision optical devices

• Harsh-environment optical applications
