The CS135 LIDAR Ceilometer measures cloud height and vertical visibility for meteorological and aviation applications. Using LIDAR (light detection and ranging) technology, the instrument transmits fast, low-power laser pulses into the atmosphere and detects back-scattered returns from clouds and aerosols above the instrument.Read More
The CS135 employs a novel split-lens design to increase optical signal-to-noise ratio over other instruments while maintaining Class 1M eye safety by integrating larger optics into a compact package. This optical design provides an alternative to traditional biaxial or common-optics designs. The optical isolation of traditional biaxial systems is maintained to increase detector sensitivity, while the low overlap height of common-optics systems is incorporated to allow measurements at close ranges.
This hybrid approach, along with state-of-the-art electronics measures cloud height and vertical visibility with high accuracy, stability, and repeatability. With a rugged environmental enclosure that protects the instrument from the harshest conditions, the CS135 measures the atmosphere with high stability and repeatability. The enclosure provides sufficient space to house a Campbell Scientific CR1000 datalogger and communications peripherals.
