Knight Optical's Custom domes for underwater cameras

Knight Optical has successfully launched a range of Stock Optical Domes for Underwater Cameras for underwater imaging, sensing and exploration applications, where protection of electronic sensor systems from harsh liquid and gas environments is essential. 

A dome is essentially a window that has two parallel curves faces. Our domes are high quality with good form error polished faces to ensure high clarity and transmission in the Visible and NIR spectrums allowing for accurate measurement.


Domes are readily mountable, optically clear and manufactured to a high standard. Available from 5mm to 200mm in diameter and 0.25 to 10mm in thickness offering hightransmission and extreme toughness for harsh environments

Typical materials

As well as fused silica, domes can be made in any of the additional materials:

  • BK7
  • PMMA Acrylic
  • Quartz
  • Sapphire
  • Germanium
  • Silicon

All our domes are checked for quality in our state-of-the-art Metrology laboratory using equipment from Trioptics, Varian and Starret allowing us to work to the highest QA standards and meet the tolerance specifications on these precision components.
