CE376 - LiDAR

CE376 – micro LiDAR

The CE376 is the latest compact, eyesafe backscatter LiDAR, featuring outstanding performances for the automated continuous monitoring of aerosols.

It operates in the visible (green) and/or in the near infrared (NIR) with options for depolarization channels for enhanced aerosol characterization.

The rugged, fully integrated system operates without shutdown, any human attendance, authorization, nor maintenance. With its thermal enclosure, the LiDAR can withstand extreme environmental conditions.

The CE376 is particularly easy to install (indoor or outdoor), to transport and even to use onboard a vehicle or a plane.

It is therefore, the perfect solution to monitor industrial dust emissions, urban pollution, volcanic ashes, and all type of aerosol particles.


Key Benefits

  • Aerosol measurements up to 18 km by night time (9 km by day time)
  • Very short blind zone (< 100 m) with an overlap from 1 km
  • Real-time “quicklook” visualization
  • Automatic extinction and backscattering profiles
  • High stability and low maintenance
  • Aerosol characterization for each layer and stratification analysis
  • Planet Boundary Layer (PBL) detection
  • Easy transportation :  Outdoor / indoor / mobile operation

Package contents

  • 1 compact automatic aerosol LiDAR CE376
  • 1 License of LiDAR control software on a USB key

Note 1: To be powered by mains.

Note 2: The telescope must be kept between +20°C and +30°C and may be installed within a thermal enclosure (not included).

** Molecular detection range

Defined, in the absence of clouds, as the distance up to which the molecular signal (of atmospheric gases) can be measured (with a signal to noise ratio superior to 1).
Aerosols and especially clouds (like cirruses) are detected well above this range (depending on their local concentration).
