Optical Glass Dome
DescriptionCustom Optical Glass Domes are precision-engineered hemispherical components available in BK7, K9 optical glass and high-grade sapphire materials. Designed for optical imaging, camera protection, underwater detection and industrial sensing systems, they deliver exceptional light transmittance, minimal distortion and superior environmental resistance.
Featuring ultra-precision polishing and optional anti-reflection (AR) coating, these domes ensure clear, high-quality optical transmission while providing robust protection against impact, scratches and harsh conditions. We offer full customization of diameter, thickness, curvature and coating to meet diverse application requirements.
Key Features
- Available in BK7, K9 optical glass and sapphire materials
- High light transmittance up to 95%+ for optimal imaging
- Precision polished surface with low distortion
- Optional AR coating to minimize reflection
- High hardness and scratch resistance (especially sapphire)
- Waterproof, dustproof and corrosion resistant
- Custom diameter, thickness and curvature options
- Stable performance in extreme environments
Available Specifications
- Material: BK7, K9, Sapphire
- Shape: Hemispherical dome
- Diameter: Customizable (10mm–300mm)
- Coating: AR anti-reflection coating
