AOI Ltd.

AOI LIMITED was founded in 1994 in Hong Kong by a team of experienced managers and engineering professionals. It started with the manufacturing of compact film cameras and then progressed to single-use cameras, single-use underwater cameras, and underwater digital camera housings. After years of intense product development and manufacturing excellence, AOI advanced as a manufacturer of professional OEM/ODM underwater camera housings and underwater electronic products.

Driven by the desire to offer a holistic and complete range of underwater imaging products, AOI decided to create products under its own brand name. In 2014, it all started with "Underwater Optics", as AOI began to develop a series of Underwater Conversion Lenses and Lens Port Systems for underwater housings and market them under the AOI brand name. Since then, the brand's reputation has grown to unimaginable heights.

The in-house vertical integrated structure from product development to after-sales services ensures full control of the products' QUALITY, DELIVERY, and COMPETITIVE PRICE.
