Optical Domes

High numerical aperture (NA) optical domes for visible and IR light using precision tooling, made from materials including zinc selenide, zinc sulfide, or germanium. Utilizing CNC processing, combined with extensive metrology capabilities, we deliver precision domes for aerospace and military applications.

Optical domes are made of two parallel surfaces that are curved, and this geometry protects and isolates critical sensors and electronics from the environment with minimal disruption to the optical path.

Optical domes can be found on forward-looking infrared systems, seeker head optical systems, in submersibles, and underwater camera systems. Airborne systems must be designed to withstand sand, intense temperature differentials, and other challenging environmental conditions. Diamond-like coatings can be used to improve performance in the field. Submersible optics must likewise be designed to withstand sea salt, spray, and more humid challenging conditions.

To ensure performance in the field, we leverage our extensive metrology capabilities to qualify every component at every step in the manufacturing process. Optical domes are difficult to measure; therefore, we have developed proprietary stitching interferometry processes to minimize errors due to reflections.

We design and manufacture our optical domes, by hand, in the United Kingdom.
