Custom Large Optical Domes Engineered for Optical Performance
Avantier’s Large Optical Domes are advanced optical enclosures engineered to protect high-precision imaging and sensing systems while maintaining exceptional optical clarity. Available in a wide range of sizes—including diameters exceeding 300 mm—these domes are ideal for aerospace, defense, marine, and industrial applications that demand both durability and precise optical performance.
Whether you need a standard hemispherical optical dome or a custom shape for specialized requirements, Avantier offers a variety of solutions crafted from premium materials like BK7, fused silica, acrylic, and sapphire.
Wavelength-Specific Transmission for Enhanced Imaging
A key feature of Avantier’s large optical domes is their ability to selectively transmit specific wavelengths of light, optimizing performance for targeted applications:
- Visible Spectrum Domes – Made from optical glass (e.g., BK7, fused silica) for high transmission and minimal distortion in camera and vision systems.
- UV Optical Domes – Constructed from UV-grade fused silica, ideal for scientific imaging and sterilization systems.
- Infrared Domes – Designed for thermal imaging, heat-seeking missiles, and infrared sensors, using materials such as:
- Sapphire
- Germanium
- Zinc Selenide (ZnSe)
- Silicon
- Infrared-compatible ceramics
Optical Domes for Full-Angle Viewing
Avantier’s domes are optimized for wide-angle viewing and multi-directional detection. When detectors are placed at the center of a half-spherical dome, incoming light strikes the dome surface normally, minimizing optical distortion and deflection. This geometry also supports the effective application of anti-reflection (AR) coatings, improving transmission across large viewing angles.

Protective Optical Domes for Demanding Environments
Avantier’s large optical domes are engineered to protect sensitive systems in extreme conditions without compromising optical integrity.
Aerospace and LIDAR Systems
- Aircraft-mounted LIDAR sensors and camera systems benefit from domes that resist high-velocity impacts from sand, hail, and bird strikes. Our domes maintain clear imaging even in harsh flight environments.
Underwater and Subsea Applications
- Submarines, underwater drones, and marine imaging systems require domes that withstand high water pressure while delivering superior optical transmission. Avantier’s domes offer robust sealing, pressure resistance, and optical performance for deep-sea environments.
Engineered Coatings and Customization
Avantier provides a broad selection of functional coatings to enhance the durability and performance of large optical domes:
- Diamond-like carbon coatings (DLC) for extreme scratch resistance
- Anti-reflective (AR) coatings for enhanced transmission
- Infrared filter coatings and metalized coatings for system-specific optical tuning
Many of our domes also include custom mechanical features for mounting, sealing, and system integration.
