UK and Ireland Road Trip

4Deep Research Scientist John Samson and RS Aqua’s Ryan Mowat visited several prominent marine science research institutes in a whirlwind trip that took in the Republic of Ireland, Northern Ireland, and the South and East coasts of England. Interest in the 4Deep microscopes is high, particularly amongst researchers with a need for a rugged, low maintenance sensor that can be deployed offshore for the identification of phyto- and zooplankton species. Unlike other plankton and particle imaging devices, the 4Deep has no moving parts and has dedicated software for the automated identification of plankton and the counting of particles. Quantitative Phase Imaging also allows it to test cell viability quickly and easily.

Putting the submersible microscope to the test at CEFAS and the Marine Institute:

4Deep Holographic Microscopes

The 4Deep Submersible Holographic Microscope allows the monitoring and recording of underwater holographic images at speeds of up to 4 knots and at 500 m depth. The microscope’s lateral resolution is < 1 μm making it possible to identify objects and organisms between 2 μm and 2 mm in size as they pass through the microscope’s 3.5 mm field of view. A desktop version of the microscope is also available with an improved lateral resolution of under 0.5 μm.
