Are your optical domes scratch resistant?

Update Time:2026/5/2

Our optical domes are designed with hierarchical scratch resistance solutions according to different application environments, meeting the wear and impact protection needs of various harsh scenarios.

Sapphire optical domes are the highest grade in scratch resistance, with Mohs hardness up to 9, second only to diamond. It has super strong anti-scratch, anti-abrasion, high temperature resistance and chemical corrosion resistance, not easy to be scratched by sand, dust and hard foreign objects in long-term outdoor, underwater and aerospace environments, maintaining long-term surface finish and clear imaging effect.

For conventional BK7/K9 optical glass domes, we can deposit high-performance DLC diamond-like carbon coating on the polished surface. The DLC coating has ultra-high surface hardness, effectively improving scratch resistance, friction resistance and anti-fouling ability, avoiding daily wear and surface scratches affecting optical transmittance.

In addition, we can match hydrophobic and anti-fog coating on the basis of scratch resistance, making the optical dome surface waterproof, oil-proof, not easy to adhere dust and water mist, reducing manual cleaning and maintenance frequency. Felix Glass can recommend the most suitable material and coating scratch resistance solution according to your installation environment, working temperature and service life requirements, ensuring the optical domes maintain stable performance for years of continuous operation.
