The dome port is a concentric lens.Dome ports greatly reduce refraction, radial distortion, axiality, and chromatic aberration.
What is optical dome lens?
Optical Dome Port Lens provide protective boundaries while allowing for a clear view between two environments. An optical dome is a lens with two concentric spheres. Sometimes they are referred to as curved planar parallel plates.
What is a dome port lenses used for?
Dome glass lenses are ideal for underwater and split-level (half over/under) photography, because they correct for aberrations that occur as light travels at different speeds above and below water.

- What does a dome do for underwater photography?
Domes are essential underwater when shooting wide angle and zoom lenses. A flat port magnifies objects the same way your dive mask does, and it turns into a port hole when shooting wide lenses.
- Which lens makes things look closer?
A concave lens makes objects look smaller and closer. Concave lenses correct nearsightedness.
- What lenses make you look bigger?}
Telephoto lens compress space, making objects appear larger and closer together than normal
