Optical domes serve as hemispheric windows that establish a protective barrier while enabling a clear field of view between two environments. Typically consisting of two parallel surfaces, these domes play a crucial role in various applications. Shanghai Optics specializes in manufacturing optical domes using a diverse range of substrates suitable for transmitting visible, infrared (IR), or ultraviolet (UV) light. Our offerings include domes with diameters ranging from 5 mm to over 200 mm, and we also accommodate custom sizes upon request.

For situations where only visible light transmission is required, choosing BK7 or fused silica as the optical dome material is recommended. BK7 offers excellent chemical durability and high transmission capabilities within the wavelength range of 300 nm to 2 µm, making it suitable for camera sensors and meteorology applications.
When it comes to UV-range light transmission, our UV-grade fused silica domes are available. These domes are designed to withstand high pressure and are particularly ideal for underwater applications. With over 85 percent transmission for wavelengths up to 185 nm, this optical glass ensures efficient UV light transmission.
Upon request, we can also manufacture acrylic domes. These domes exhibit reduced light scattering compared to BK7 or fused silica options while maintaining a high level of durability.
Avantier specializes in the production of custom optical domes using a wide range of substrates suitable for transmitting visible, IR, or UV light.

Optical Domes: The Unseen Heroes of Optical Systems
In the realm of optical systems, where precision and clarity are paramount, optical domes play a crucial yet often overlooked role. These transparent, protective enclosures are designed to shield optical components from external elements while ensuring optimal performance. From cameras and sensors to navigation systems and scientific instruments, optical domes find applications across various industries. In this article, we will explore the essential attributes that make optical domes indispensable in optical technology.
Crystal Clear Protection
One of the primary functions of optical domes is to provide a protective barrier for delicate optical components without compromising clarity. Composed of high-quality materials, such as optical glass or transparent polymers, these domes offer exceptional optical transparency. This crystal-clear protection allows optical systems to operate efficiently while safeguarding sensitive components from dust, moisture, and other environmental factors.
Enhanced Durability and Strength
Optical domes are engineered to withstand challenging conditions, making them an integral part of optical systems in diverse environments. Whether it's in aerospace applications, underwater exploration, or harsh industrial settings, optical domes provide enhanced durability and strength. The materials used in their construction are carefully selected to resist scratches, impact, and corrosion, ensuring the longevity and reliability of the optical system.

Reduced Distortion and Aberrations
Maintaining optical integrity is vital in applications where precision is non-negotiable. Optical domes are designed to minimize distortions and aberrations that can occur when light passes through different mediums. The careful engineering of these domes ensures that optical signals remain clear and undistorted, allowing for accurate data collection and image capture in fields like photography, astronomy, and remote sensing.
Weathering the Elements
In outdoor applications, optical systems are exposed to a wide range of environmental conditions. Optical domes act as a shield against adverse weather elements such as rain, snow, and wind. This weather-resistant feature is particularly crucial in surveillance cameras, scientific instruments, and military optics, where the reliability of data acquisition depends on the ability to withstand the elements.
Seamless Integration into Design
Optical domes are not just protective barriers; they are also seamlessly integrated into the design of optical systems. The careful consideration of shape, curvature, and material properties ensures that optical domes complement the overall design of the system. This integration enhances both the aesthetic appeal and functional performance of the optical device.
Applications Across Industries
The versatility of optical domes is reflected in their widespread use across various industries. In aviation, optical domes protect sensors and cameras on aircraft, providing clear vision for navigation and surveillance. Underwater vehicles and submersibles rely on optical domes to maintain optical clarity in the challenging underwater environment. Furthermore, optical domes are integral components in scientific instruments like telescopes and spectrographs, where precision is paramount.
Customization for Specific Requirements
Not all optical systems are created equal, and optical domes are designed with this in mind. Manufacturers offer customization options to meet the specific requirements of different applications. Whether it's a unique shape, a particular material, or special coatings to enhance performance, optical domes can be tailored to suit the demands of diverse optical systems.
Conclusion: The Unseen Guardians of Clarity
In conclusion, while optical domes may go unnoticed in the grand scheme of optical technology, their importance cannot be overstated. These unassuming components serve as the guardians of clarity, protecting sensitive optical elements and ensuring optimal performance in a myriad of applications. From aerospace and defense to scientific research and consumer electronics, optical domes play a pivotal role in enhancing the reliability and longevity of optical systems.
