What are optical domes used for?

Professional optical domes are core precision optical protective components widely deployed across global industries including security surveillance, underwater marine engineering, aerospace defense, industrial machine vision and medical optoelectronic equipment.

 

Manufactured from high-purity BK7/K9 optical glass, synthetic sapphire and fused silica raw materials, our optical domes feature ultra-high visible and infrared light transmittance, excellent optical uniformity and minimal wavefront distortion. The streamlined spherical structure can effectively isolate external interference such as dust, rain, snow, sand, moisture and mechanical impact, ensuring the internal optical lens and sensor maintain stable, high-definition imaging performance in long-term outdoor and harsh working environments.

 

At Felix Glass, every optical dome is processed by ultra-precision surface polishing, strict annealing treatment and multi-layer optical coating customization. We support AR anti-reflective coating, IR infrared coating, DLC wear-resistant coating and hydrophobic anti-fog coating, greatly improving light transmittance, scratch resistance and environmental adaptability. Whether for standard commercial monitoring equipment or high-end customized aerospace optical systems, our optical domes can provide reliable long-term protective solutions.
