Zen Underwater

Zen Underwater was founded in 2007 with one goal in mind, to design and develop the highest quality optical glass port available in the underwater imaging market. Our products have since been used by professionals in all corners of the world and have been touted by the best underwater photographers as being the finest dome ports available.

Zen ports start with the best optical glass available. The surface is coated with a magnesium fluoride broadband anti-reflective coating to minimize reflections along with a proprietary scratch resistant coating to control lens flare. This results in one of the most optically pure glass ports available, with an amazing 99.7%+ transmissive value for true distortion free images.

We are located in South Florida and have the amazing opportunity to put our equipment to the test every week on the beautiful Florida reefs and around the world. We are all divers and underwater photographers who contribute our experience and knowledge to the development of each product. This gives us the unique ability to not only offer superior products, but to share our real world experience and advice with all our customers.
