Soletop's Lidar products benefit from space grade technology. Products are reliable, easy to use, and budget friendly.
- MODEL SRL 300 Raman Lidar
The SRL300 Raman Lidar is carefully designed to study particles and aerosol. Optical and physical properties of a particle can be measured and classified. The typical application is in meteorology, measuring cloud height and distribution.
Lidar is the optical equivalent of radar(LIDAR is an acronym of Light Detection And Ranging) an active remote sensing technique.
SRL-300 LIDAR is based on the particles of elastic and inelastic (Raman) backscatter. A pulsed laser beam is emitted into the atmosphere.
The light is scattered by particles or molecular in the atmosphere. Some of the light reaches the receiving telescope where it is amplified and digitized. Interactions with nitrogen, water vapor(Raman scattering) and atmospheric gases, aerosol(Mie/Rayleigh scattering) can provide a wealth of information about the atmosphere.
SRL-300 LIDAR offers a well-established method of determining the vertical profile of the aerosol extinction coefficient independently from the aerosol backscatter coefficient.
SRL-300 LIDAR is suitable for multiple atmospheric monitoring applications, including advanced cloud analysis. We provide complete lidar solutions, including all hardware and software necessary to operate the system and analyses the data.

- MODEL SDIAL Differential Absorption Lidar
SDIAL is a type of Lindar profiler that takes measurements based on the difference of absorption and scattering of two laser beams. It can measure the profile and distribution of multiple pollution elements such as SO2
etc. Soletop offers a powerful analysis software package to measure, archive, and visualize these critical parameters.
