The Best Lenses For Subsea Cameras: LiquidOptics

Quality subsea inspections and research rely on capturing the best digital stills and 4K video. Using the right optical lens can make all of the difference to the performance of your subsea camera. 


At SubC, all of our cameras use scratch-resistant sapphire lenses. They are also paired with water-corrected, Ivanoff-inspired LiquidOptics, a technology that was created by and unique to SubC. Qualified for performance by a 3rd party, LiquidOptics provides an extremely durable, impact-resistant, and high-performing lens.

Why Are LiquidOptics Lenses Best for Subsea Imaging?

LiquidOptics are best for subsea imaging because they offer all of the advantages of a dome port with a flat focal plane. With LiquidOptics your images and video will have:

  • Accurate colour depth

  • Very low distortion

  • High sharpness

  • Minimal chromatic aberration

  • An afocal design that removes issues related to depth of field and focus


Flat Port Lenses Vs. LiquidOptics Lenses

We’ve had our lenses tested and proven by a 3rd party to show just how superior LiquidOptics are. See for yourself!

Less Distortion 

LiquidOptics ensure your photos have low distortion compared to a flat port optics. In the comparison below, you can see that the axis is more distorted in the image taken with a flat port compared to LiquidOptics.

Chromatic Aberration

The lower the chromatic aberration the better. The comparison shows there is clear colour bleeding and chromatic aberrations in the image taken with a flat port.

Sharpness

The sharpness is much higher in in the LiquidOptics lens. Sharp images have more detail, which is particularly important for any application requiring data processing such as photogrammetry, 3D modelling and machinevision. In these applications LiquidOptics is uniquely effective.
