Laser Diagnostic Instruments

Imagine. Create. Transform.

LDI has been researching & developing remote-sensing technologies since 1991.

The best instruments are built from constant improvements: thoroughly listening & responding to user feedback.

LDI is an established R&D company that has been developing and building sensors that analyze substances in real time. Combining photonics with advance algorithm in software analysis, our instruments excel at detecting specific molecules using non-contact technology. We have chemists, electricians, and optical engineers who help realize our products, all done in-house in Estonia.

Being in business since 1991, LDI originally started by building sophisticated aircraft and ship-mounted laser based (LiDAR) systems that can detect sub-surface oil spills over many miles. The demand for a simpler, more flexible device that would catch early surface spills in real-time led us to develop ROW, which is now installed in industrial and public water facilities around the world.

We hold nine core technological patents and continue to innovate our products. We aim to ensure that industrial processes remain safe and risks to the environment are minimalised. Our non-contact technology puts our products at the forefront of easy to use instrument for water monitoring. Because remote sensing is our passion, you can count on us standing by your side for years.
