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.

CE376-GGreen532 nm
CE376-GPGreen with depolarizationInformation on the presence of aspherical particles (ashes, sand, cirruses) in each layer
CE376-GNGreen + NIRInformation on the particle size in each layer
CE376-GPNGreen with depolarization + NIRInformation on the presence of aspherical particles (ashes, sand, cirruses) in each layer

** 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).
