Overview

The Submersible Microscope allows you to quickly and easily observe micro-organisms and particles up to a depth of 5 kilometres (in custom models).

Applications

Benefits

Pulsed Laser
User control of laser pulse, with duration to 500 nanoseconds, holograms now capture rapid (4 m/s) movements, and has been tested at tow speeds of 8 knots

Real-time
Real-time in-situ observation of particles and micro-organisms in all aquatic environments

Portable
Lightweight, easy to deploy, rugged

High Flow Capabilities
Can be towed at 8 knots (4 m/s), stationed in rivers

Low maintenance
Easy to clean with no pump or tubes, making biofouling less of an issue

Fast Tracking
Up to 22 images per second to capture tracking dynamics of fast moving objects

Save Time
Real-time hologram reconstruction with our patented algorithm available in all our software

Go Deeper
Pressure rated for 0-500m, with a cable depth of 100m. Up to 5000 meters in custom models
