sapphire dome lens with hole


Optical domes are hemispheric windows that provide a protective boundary while allowing a clear field of view between two environments. They are typically made with two parallel surfaces. He Rui Optics manufactures optical domes in a wide variety of substrates, suitable for visible, IR, or UV light.

Well-suited for infrared optical dome applications, sapphire transmits up to eighty percent of light in the 2-5 µm wavelength range. It is extremely resistant to scratching and abrasion, making it an excellent choice for defense applications and high-pressure environments, such as underwater camera systems for deep sea exploration.

  • High strength, high hardness, high temperature resistance

  • Abrasion resistance, corrosion resistance

  • Maximum diameter 600mm

  • Good light transmission performance (150 ~ 5500 nm)

  • Excellent electrical insulation performance, and good mechanical properties
