Dome lens

10 Apr 2018

A dome is composed of two parallel surfaces, which are curved. Compared with any other optical components, it has no optical effect in the optical design.

Domes can be used in pods and missiles. They are designed to protect electronic detectors and sensors from moving particles, water and corrosives while extending their viewing angles. Also they are ideal for underwater environments and in applications such as camera dome ports and submersible window.

We provide hemisphere domes and hyperhemisphere domes. They are produced by polishing and can be manufactured to specification from a variety of materials. Optical glass, fused silica, sapphire, IR crystals, as well as transparent ceramic are commonly used.

 N-BK7 or equivalent, offers a tough, cost effective solution for visible range applications while Fused Silica is ideal for wavelengths below 400nm.

 Key features:

  • With different shape, hemisphere, hyper hemisphere, cutting …
  • A variety of materials available
