• Sapphire biconcave lens
• Sapphire spherical lens
• Sapphire aspheric lens
• Sapphire cylindrical lens

The Charactericstic Of Sapphire Lens

Sapphire lenses are crafted from synthetic sapphire, delivering exceptional performance under high-temperature, high-pressure, and high-abrasion conditions.

• First, sapphire lenses offer excellent transmittance across the ultraviolet to mid-infrared spectrum.
• Additionally, sapphire lenses feature high refractive index and exhibit slight birefringence, making them particularly suitable for optical systems where crystal orientation is critical.
• With a Mohs hardness of 9, sapphire lenses are highly resistant to wear and scratches.
• Their exceptionally high melting point renders them ideal for high-temperature applications.
• Furthermore, sapphire lenses possess high thermal conductivity, enabling efficient heat dissipation, making them particularly suitable for high-power laser systems.
• We can manufacture large-sized sapphire lenses with diameters up to 1000mm. Our large sapphire lenses exhibit minimal deformation. Although machining, polishing, grinding, and coating demands are stringent, we can address all technical challenges and ensure the sapphire lenses qualify as high-pressure and high-vacuum windows.

Application Of Optical Sapphire Lens

• Laser System Focusing Lenses
  Sapphire, due to its physical properties, can withstand high laser damage thresholds and exhibits high transmittance across the ultraviolet to infrared spectrum. It is suitable for use as laser cavity windows, output lenses, or focusing lenses in laser systems, ensuring efficient transmission of laser energy.
• Infrared Thermal Imaging Systems
  Sapphire offers excellent infrared transmittance in the 2-5 micron range and possesses high hardness. It serves as an ideal focusing lens for infrared cameras, suitable for night vision, infrared thermography, and similar applications.
• Medical Endoscopes
  Medical endoscopes frequently encounter acidic/alkaline fluids and mechanical friction. Sapphire lenses function as end-face windows or focusing lenses for medical endoscope probes. This ensures clear medical imaging while preventing scratches and extending equipment lifespan.
