Raymetrics has been manufacturing high technology solutions for studying the atmosphere for more than a decade. We design and build a range of laser-based remote sensing instruments (LIDARs) which are suitable for a variety of purposes, including academic uses (such as scientific studies of the atmosphere), commercial uses (such as dust trackers for use in open pit mines), and operational uses (such as our Raman depolarization LIDAR optimized for volcanic ash detection).

We have sold our products all across the world, including in the USA, India, China, Africa, South America, South East Asia and Europe. The company has built up an extensive client list, which includes such prestigious organizations as the European Space Agency (ESA), the UK Met Office, Meteo France, and the German Aerospace Centre (DLR).
