Designing a low-cost wide lens underwater camera



After much success with our Fluid Filled Pressure Compensating Underwater Camera (FPUC) we have decided to develop a wide angle version. Most of the electronics and the design remain the same.

We have modified our internal camera housing (which protects the sensor from mineral oil) to accommodate the larger lens. As similar with the prior version, the camera board is enclosed in an epoxy potting.



The outer housing acrylic viewing window has been enlarged to support the larger field of view. Internally, a custom 3D printed board holds all the electronics together and fits snuggly inside the housing.


The results are fantastic and we do wonder why we didn't do this sooner.

AusOcean is a not-for-profit ocean research organisation that supports open source practices. Open source approaches to tackling environmental issues means embracing collaborative tools and workflows which enables processes and progress to be fully transparent. A critical aspect of working open is sharing data not only with your immediate team but with others across the world who can learn, adapt and contribute to collective research. By contributing to, and supporting open practices within the scientific community, we can accelerate research and encourage transparency.
