Optical glass dome
Optical glass domes are essential components that are widely used in underwater detection equipment. They are made of optical glass, which is known for its superior optical properties, such as high transparency, refractive index, and low dispersion. These properties make the glass substrates ideal for designing lenses and other optical elements used in underwater detection equipment.The optical dome is an important component in submersibles, it has a wide angle and can be protective of the deep-sea camera.
Optical glass domes are essential components of underwater detection equipment due to their ability to withstand the harsh underwater environment. The domes are constructed using materials that can withstand high pressure, corrosive saltwater, and extreme temperatures. The optical glass used on the domes is chemically resistant, meaning that it can withstand exposure to harsh chemicals without being damaged.
Our Company can provide optical glass dome with diameters from 5-500mm (accuracy up to 20-10, 1/10-1L@633nm),coating AR, BBAR, AF or upon request.
