Sapphire Convex Lens for medical optics, laser optics, and imaging applications
  • Boasting remarkable hardness, strength, and wear resistance.
  • Exhibiting outstanding thermal conductivity and resistance to heat
  • Demonstrating exceptional chemical stability.
  • Offering superb transmission bandwidths from ultraviolet (UV) to infrared (IR).
  • Providing a range of options including blank substrates, anti-reflective (AR) coated pieces, and precision windows.
  • Sapphire exhibits excellent light transmission within the 0.20 to 5.50μm wavelength range, making it highly suitable for laser and infrared optical applications. Commonly employed in endoscopes, watch glass, optical lenses, surface acoustic wave filters, military infrared windows, optical filters, observation windows for high/low temperatures, and cosmetic instrument windows, among others. We offer services including anti-reflection, high-reflective, dielectric, filter, and metallized films.

    Sapphire optical lenses are utilized to manipulate the direction of light transmission, thereby controlling imaging accuracy and angles. With its superior transmittance, sapphire lenses offer extended lifespan and broader spectral adaptability compared to optical glass.

    We specialize in fabricating various types of sapphire convex lenses to meet user specifications, including plano-convex, double-convex, and bi-convex lenses.

  • We offer custom anti-reflection coatings tailored to your specified wavelength.
  • Although sapphire transmits ultraviolet light, it may exhibit fluorescence under intense ultraviolet sources. Therefore, it is most suitable for applications within the visible to infrared wavelength range.
  • Ensure to wear laser safety goggles when inspecting optical paths and adjusting optical axes.
