Optical dome are hemispheric windows which provide a protective boundary while allowing a clear field of view between two environments. Dome lens are typically made of two parallel surfaces.
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.

People also ask
- 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
