Custom aspheric sapphire dome
Aspheric sapphire dome is a dome-shaped piece of synthetic sapphire crystal that does not have a perfectly spherical surface. Unlike a spherical dome, which has a uniform curvature, an aspheric dome’s curvature varies across its surface. This non-spherical shape is specifically engineered to reduce optical distortions, such as spherical aberrations, making it highly beneficial in advanced optical applications.
Aspheric sapphire domes combine the durability and scratch resistance of sapphire with advanced optical performance, offering clear advantages in applications requiring precision imaging or light transmission.
Aspheric sapphire domes are used in a variety of fields where precise optical performance, durability, and resistance to harsh conditions are crucial. Aspheric sapphire domes are valued across diverse fields for their ability to enhance image quality, minimize optical distortions, and withstand challenging conditions, making them ideal for applications that require both precision optics and durability.
We have rich experience in manufacturing custom optical sapphire domes. We can produce a variety of custom sapphire domes, including sapphire hemispherical domes, sapphire hyper-hemispherical domes, kerfs sapphire domes, spherical sapphire domes, aspheric sapphire domes, sapphire domes (Sapphire fairing radome), U-shape sapphire domes, conformal sapphire domes, and special–shaped sapphire hyper-hemisphere dome.
The diameter of HY custom sapphire domes can be manufactured up to Φ390mm.

Advantages of Aspheric Sapphire Domes
1. Reduced Optical Distortion
1). Minimized Spherical Aberration: Spherical surfaces can cause light to bend unevenly at the edges, creating blurriness or distortion, especially in lenses. Aspheric shapes correct for these aberrations, allowing the dome to focus or transmit light more accurately.
2). Enhanced Clarity: By reducing distortion, aspheric sapphire domes allow for sharper images and clearer transmission of light, making them ideal for high-precision optics, like advanced cameras and sensors.
2. Improved Light Transmission and Focus
1). Wide Field of View with Sharp Focus: Aspheric domes provide a broad viewing angle with enhanced clarity, which is particularly beneficial in optical systems that require both a wide field and detailed resolution, such as in underwater imaging or space telescopes.
2). Efficient Light Gathering: The aspheric design allows for more effective light gathering and focusing, maximizing the performance of optical instruments that need to capture faint or distant light sources.
3. Durability and Scratch Resistance
Similar to spherical sapphire domes, aspheric sapphire domes retain the material advantages of sapphire, including high hardness, scratch resistance, and chemical inertness. This makes them suitable for harsh environments or applications requiring long-term durability.
4. Enhanced Aesthetic for High-End Products
Aspheric sapphire domes are also used in high-end products, such as luxury watches, where the unique curvature adds both functional clarity and aesthetic appeal.
Applications of custom aspheric sapphire dome
1. Aerospace and Defense
1). Optical Sensors and Imaging Systems: Aspheric sapphire domes are often used in sensors and imaging systems in satellites, drones, and military equipment. The dome’s design provides a clear, wide field of view and accurate light transmission, which is vital for navigation, targeting, and reconnaissance.
2). Protective Covers for High-Altitude Cameras: Sapphire domes serve as protective covers for optical systems that must withstand extreme temperatures, pressure changes, and exposure to particulates in high-altitude environments.
2. Underwater and Marine Equipment
1). Underwater Cameras and Imaging Systems: Aspheric sapphire domes are used in underwater cameras and ROV (remotely operated vehicle) sensors, where they enhance optical clarity and field of view. Their durability and resistance to pressure make them ideal for deep-sea exploration.
2). Submersible Optical Windows: In scientific and commercial diving equipment, aspheric sapphire domes provide clear, distortion-free viewing windows that withstand high-pressure environments.
3. High-End Optical Systems
1). Cameras and Lenses: Aspheric sapphire domes are used in advanced camera lenses, particularly those requiring distortion-free imaging and high resolution. Their aspheric design minimizes spherical aberrations, ensuring clear, sharp images across a wide field.
2). Microscopes and Telescopes: In scientific instruments where clarity and precision are essential, aspheric sapphire domes improve image quality by focusing light more effectively, allowing for detailed observation and imaging.
4. Medical Imaging and Diagnostics
1). Endoscopy and Surgical Instruments: In medical imaging devices, such as endoscopes, aspheric sapphire domes provide high clarity and precise light transmission, allowing for better visualization during procedures. The material’s durability and resistance to chemical sterilization ensure safety and longevity in medical environments.
2). Optical Sensors for Diagnostics: For advanced diagnostic tools that rely on precise optical sensing, aspheric sapphire domes improve the accuracy of measurements and imaging, aiding in better diagnostic outcomes.
5. Automotive and Transportation
1). Advanced Driver Assistance Systems (ADAS): In automotive systems that rely on optical sensors, such as cameras for parking, lane-keeping, or autonomous driving, aspheric sapphire domes offer a robust, clear lens cover that reduces distortion and improves image quality.
2). Aerospace Navigation and Tracking Systems: Aspheric sapphire domes are also employed in navigation systems in planes and autonomous vehicles, where precise and distortion-free imaging is crucial for accurate readings.
