A dome is an optical window composed of two parallel curved surfaces. Domes are commonly used in defence applications and often in extreme environments such as submersible ROVs.
For this reason our domes offer both high transmission as well as durability. Other applications for our domes include visible-range domes for pyranometers and infrared-range domes for pyrgeometers, and as high pressure viewports in underwater cameras and submersibles.
BK7 domes are available directly from stock, and are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability. Our custom BK7 domes are practically free from bubbles and inclusions, making them perfect for high performance visible applications.
Custom domes available from 5mm to over 200mm diameter.
Parts may be AR coated for improved transmission. Information on alternative coatings available on request.
Although typically manufactured from BK7, UV Fused Silica or Sapphire, other materials are available on request.
Domes may be manufactured with or without flanges for ease of installation.
Certain materials may be toughened to improve durability in harsh conditions as an alternative to sapphire.
