Our Dome Lens is an optical window composed of two parallel curved surfaces. Dome lenses are commonly used in meteorology applications, pyranometers, defence applications and often used in high pressure viewports in underwater cameras and submersibles.For this reason our dome offer both high transmission as well as durability. Other application for our dome include visible-range domes for pyranometers and infrared-range domes for pyrgeometers, and as high pressure viewports in underwater cameras and submersibles.
BK7 or K9L domes 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.

Fatih Birol, chief economist of the International Energy Agency, said at a two-day International Energy Agency ministerial meeting in Paris today that the reduction in investment in oil and gas projects may push up oil prices in the next five years.
The International Energy Agency estimates that in order to meet global energy demand by 2035, global energy projects will require 38 trillion US dollars of investment by 2035, which is 15% higher than the 33 billion US dollars projected by the International Energy Agency in 2010.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.
Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.

IEA: Arab Spring destroys investment in oil and gas projects
According to a Reuters report on October 18 in Paris, the International Energy Agency (IEA), headquartered in Paris, France, said today that while some countries in the Middle East have shifted their focus to meet the increasing domestic energy demand, "Spring" destroyed the investment in oil and gas projects in this area.
