Optical Sapphire Domes Product Overviw

Sapphire domes are spherical or hemispherical domes made from sapphire. Primarily used for focusing, collimating, or guiding light beams, sapphire offers high-temperature resistance, corrosion resistance, and scratch resistance, while also providing protective properties. Coligh specializes in manufacturing a wide range of small to medium-large domes, with diameters ranging from 5mm to 500mm. Our product lineup includes sapphire hemispherical domes, sapphire superhemispherical domes, and sapphire cut-out domes. They are typically used in high-end cameras, sensors, or as optical windows.

The Optical Sapphire Domes Type We Manufactures

We can manufacture various types of domes according to customer drawings and requirements. Currently, our company can produce domes including, but not limited to:

• Flanged Sapphire domes
• Chamfered edges Sapphire domes
• Sapphire aspheric domes
• Sapphire super-hemispherical domes

Optical Sapphire Domes Product Characteristic

• Sapphire dome covers are crafted from high-purity optical sapphire single crystals, featuring a Mohs hardness of 9. They offer exceptional scratch and impact resistance while maintaining high transmittance across the ultraviolet to mid-infrared spectrum. Additionally, sapphire’s inherent properties provide resistance to high temperatures, corrosion, and scratches, making it well-suited for extreme environments.
• We can process sapphire hemispherical domes in various shapes and precision levels, maintaining high accuracy even for large-sized sapphire domes.
• In terms of dimensions, we can fabricate hemispheres, superhemispheres, and aspherical shapes. Additionally, we can design flanges, chamfers, and beveled edges.
• Due to sapphire’s inherent physical properties, it can withstand damage from high-power lasers, making it highly suitable for laser windows, detector protection windows, and similar applications.

Custom Capability Of Optical Sapphire Domes

Application Of Optical Sapphire Domes

• Aerospace
  In aerospace missile flight, the nose cone must withstand extreme launch pressures, dust, and violent impacts. Sapphire domes serve as missile guidance heads, shielding internal sensors to ensure missile functionality in harsh environments.
• Deep-Sea Exploration
  In the deep ocean, seawater is corrosive, and reliable deep-sea operations require clear imaging. Sapphire serves as the window for underwater cameras and scanning systems, protecting sensors while withstanding external water pressure and maintaining shape integrity at extreme depths.
• Semiconductor Equipment Protection Windows
  In semiconductor processing, laser equipment, and spectrometers, sensors and devices require 24/7 operation. Sapphire domes installed in these instruments serve as observation windows for semiconductor etchers and laser reaction chambers, extending equipment lifespan.
