Sapphire Concave Lens for medical optics, laser optics, and imaging applications
  • Experience extreme hardness, strength, and wear resistance with our Sapphire Concave Lens.
  • Benefit from excellent thermal conductivity and heat resistance for optimal performance in high-temperature environments.
  • Enjoy exceptional chemical stability, ensuring long-lasting durability.
  • Choose from a variety of options, including blank substrates, AR-coated pieces, and precision windows, to meet your specific needs.
  • Sapphire offers excellent light transmission within the 0.20 ~ 5.50μm wavelength range, making it an ideal choice for laser and infrared optical applications. Our products find wide usage in various fields, including endoscopes, watch glass, optical lenses, surface acoustic wave filters, military infrared windows, optical filters, high/low temperature observation windows, and cosmetic instrument windows. We provide a range of services, including anti-reflection, high-reflective, dielectric, filter, and metallized film coatings.

    Sapphire optical lenses are commonly employed to control the direction and accuracy of light transmission. With its superior transmittance, sapphire lenses offer longer lifespan and broader spectral adaptability compared to optical glass.

    We specialize in processing different types of sapphire convex lenses according to user specifications, such as plano concave lenses, double concave lenses, bi-concave lenses, pcv cylindrical lenses, and bcv cylindrical lenses.

  • We offer customized anti-reflection coatings for specific wavelengths as per your requirements.
  • Sapphire demonstrates UV light transmission, although it may exhibit fluorescence under intense UV sources. Hence, it is most suitable for applications involving visible to infrared wavelengths.
  • Please ensure the use of laser safety goggles while inspecting the optical path and adjusting the optical axis.
