Sapphire optical lenses AL2O3 Customizable High-temperature resistance DSP 60/40
Single crystal optical grade Sapphire lenses are ideal for demanding applications (such as high-power laser systems) and harsh environments because of their extreme surface hardness, high thermal conductivity, high dielectric constant, and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamond and, because of their structural strength, Sapphire crystal lenses can be made much thinner than other common materials. Chemically, Sapphire is single crystal aluminum oxide(Al2O3) and is useful in a transmission range from 0.15 to 5.5μm.
The Character of Sapphire Optical Lenses:
Extreme Hardness: Sapphire ranks 9 on the Mohs scale of hardness, second only to diamond. This makes it highly scratch-resistant and durable.
Optical Clarity: Sapphire lenses offer excellent optical clarity and high transparency across a wide range of wavelengths, from ultraviolet (UV) to infrared (IR), making them ideal for high-precision optical systems.
High Thermal Conductivity: Sapphire has good thermal conductivity, allowing it to dissipate heat effectively, which is beneficial in high-power optical applications like lasers.
Chemical Resistance: Sapphire lenses are highly resistant to most acids and alkalis, making them ideal for use in harsh chemical environments.
High Strength: Despite being hard and durable, sapphire is also strong and resistant to impact, which enhances its suitability for industrial and scientific applications.
High Refractive Index: Sapphire lenses have a relatively high refractive index (about 1.76 at visible wavelengths), which contributes to their effectiveness in focusing light.
Temperature Resistance: Sapphire lenses can withstand extreme temperatures, maintaining their integrity in both high- and low-temperature environments.
