The Lufft CHM 15k is a LIDAR cloud height sensor based on a single wavelength backscattering technique. It detects various cloud layers (max 9), cloud penetration depths, issues the Sky Condition Index, vertical field of view (VOR), aerosol layer heights, boundary layers and aerosol backscatter profiles with a range of up to 15 km.
The sensor achieves excellent signal quality thanks to its stable wavelength and its Nd:YAG narrow-beam microchip laser operating in the 1064 nm range. In addition, its technology enables efficient daylight suppression and reduces temperature fluctuations to a minimum.
Due to its pulse energy and laser frequency it is eye-safe and classified as a 1M laser product.
Moreover, the CHM 15k features a user-friendly design that enables unattended, continuous operation.
The CHM 15k is a state-of-the-art solution for today’s diverse requirements of atmospheric research. It is suitable both as a sophisticated aerosol research instrument and as part of a large measurement network.
