Dome Lens
Under water optical dome

Changchun Long Ze Precision Optics Co., Ltd is a leading manufacturer of optical components in China.

Our optical domes are widely used in solar energy measuring instrument, underwater camera and high-pressure window of submersible. It provides long-term protection for measuring instruments in natural and exposed environment. The stability of our material protects the instruments from erosion of natural environment. It can also work at depth of 5000m under the water. Because of the stability of dome, it can greatly protect the proper functioning of underwater camera and provide high light transmittance with a 180° field of view, which is one of the most important elements for deep-sea detection.

During the last few years, weve delivered more than 15,000 dome lenses. Through years of accumulation, we possess many kinds of ready-made tools and stocks sized from 24mm to 100mm. We can ensure the fastest delivery date, the best quality and the most optimal price whenever you need.

Our processing range

As for a dome with diameter less than 50mm, the concentricity is within 0.02mm. We are also developing dome with concentricity less than 0.01mm.

Dome lens is also a kind of special meniscus lens, whose concentricity cant be corrected by edging. Its production is also a combination of accurate production equipment and perfect coordination of radius and center thickness. We consummate our process through mass production.Only under perfect situation can we manufacture high- precision dome lens.
