Custom Sapphire Domes & Optical Domes for Optical Equipment - Felix Glass

We are a leading manufacturer of precision optical components, specializing in custom-engineered optical dome lenses for demanding industrial, aerospace, marine, and scientific applications. Our optical domes are designed to provide superior optical clarity, robust environmental protection, and reliable performance for critical optical systems, from underwater cameras to high-precision surveillance equipment.

 

Diverse Material Solutions for Every Application

 

We offer a comprehensive range of premium optical materials to meet diverse performance and environmental requirements:

 

- BK7/K9 Optical Glass Domes: The industry standard for visible-spectrum applications, delivering exceptional light transmission, consistent refractive index, and excellent mechanical stability, ideal for general-purpose surveillance, industrial sensors, and consumer optical devices.

- Sapphire Domes: Engineered from single-crystal sapphire, these domes offer extreme hardness (9 Mohs), unmatched scratch resistance, and broad spectral transmission (UV to IR), making them perfect for harsh underwater, aerospace, and high-pressure environments where durability is paramount.

- Fused Silica Domes: Featuring outstanding UV transmittance, ultra-low thermal expansion, and superior chemical resistance, these domes are the top choice for UV optical systems, high-temperature laser applications, and corrosive industrial environments.

 

Specialized Design & Customization Options

 

Our optical domes are fully customizable to your exact project specifications, with specialized designs tailored to unique system requirements:

 

- Slanted Edge Optical Domes: Precision-engineered with angled edges to minimize reflection, reduce stray light, and optimize optical performance for edge-mounted and compact optical systems, ideal for space-constrained industrial equipment.

- IR Optical Domes: Optimized for infrared spectral transmission, these domes deliver high clarity in thermal imaging, night vision, and infrared sensor applications, ensuring accurate detection and imaging in low-light and harsh conditions.

- Optical Ball Domes: Spherical domes with 360° panoramic viewing capability, designed for underwater robots, panoramic surveillance cameras, and omnidirectional optical systems, providing unobstructed all-around visibility.

- Protective Optical Domes: Robust, impact-resistant domes engineered to shield sensitive optical lenses and sensors from water, dust, impact, and extreme environmental damage, extending the service life of critical optical equipment.

 

OEM & ODM Manufacturing Excellence

 

As a professional optical component manufacturer, we provide end-to-end OEM & ODM Manufacturing for Optical Lenses and domes. Our in-house engineering team collaborates with clients to develop custom solutions, including tailored sizes, curvatures, thicknesses, surface finishes, and advanced coating options (AR/IR/anti-fog coatings). We support both small-batch prototyping and large-scale mass production, with rigorous quality control at every stage to ensure compliance with international optical standards.

 

Uncompromising Quality Control

 

Every optical dome undergoes a rigorous multi-stage inspection process, including dimensional accuracy verification, surface quality testing, spectral transmittance analysis, and environmental reliability testing (temperature, pressure, corrosion resistance). This ensures consistent optical performance, long-term durability, and zero defects for even the most demanding applications, from deep-sea exploration to aerospace exploration.

 

Our optical domes are trusted by global clients across marine, aerospace, industrial automation, and scientific research industries. With factory-direct pricing, fast lead times, and dedicated technical support, we are your reliable partner for high-quality custom optical dome solutions.
