What is optical dome lenses?

Optical Dome Port Lenses 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.

VY Optics provides dome lenses of various materials.

What is a dome port lens 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. 
   
• Do dome cameras have night vision?
  Most dome cameras have a built-in infrared LED light for night vision, which enables them to provide high quality video surveillance. Apart from that, dome cameras are generally encased in durable covers to avoid vandalism and damage, making them an ideal option when using in exposed areas.
   
• What is a dome in photography?
  The dome port is preferable for underwater photography with wide lenses, while the flat port should be utilized if the shot starts or ends above water, or if you need to capture a close-up with a long lens. Dome Port – The dome port is a concentric lens that acts as an additional optical element to the camera lens.
   
• What is the best shape for a dome?
  Triangles are the strongest shape because they have fixed angles and don't distort very easily. Michael Busnick, owner of American Ingenuity, which sells dome homes, says triangles are key to making domes strong.
   
• Why is dome shape so strong?
   Domes are so strong because of their shape. The dome shape distributes the weight/pressure/force evenly over the entire dome shape, which reduces the load on a single point. We normally think of eggshells as brittle or that they tend to break
   
• What material are camera domes?
  Slump molded glass domes are typically made from the same types of quality glass as ground and polished domes. A big advantage of the slumping process is slump molded glass domes can be made from readily available, relatively low cost "float" type glass such as soda lime, borosilicate or "Gorilla®" type sheet glasses.
   
• What is camera lens glass made of?
  Glass is the most common material used to construct lens elements, due to its good optical properties and resistance to scratching. Other materials are also used, such as quartz glass, fluorite, plastics like acrylic (Plexiglass), and even germanium and meteoritic glass.
   
• How far can a dome camera see?
  The visual range of a security camera depends on a variety of features. Generally speaking, security cameras have a range of anywhere between 10 and 70ft during the day. Some advanced night-vision security cameras have a range of 100-200ft!
