Carlson Scan2K Scanner

carlson scan2k laser scanner

The Carlson Scan2K bridges the gap between small, light-weight, short-range sensors and large, long-range, pulsed time-of-flight scanners. Built with surveyors in mind, the Carlson Scan2K has a user-friendly on-board operator interface with menu-driven operations for quickly collecting and referencing data.

With an integrated high-resolution camera, inclinometers, a compass, a L1 GNSS receiver, and weather-proof housing, the Scan2K can be deployed in many environments and orientations. Whether on a tripod, vehicle, or moving platform, the outstanding performance of the Scan2K makes it the most versatile terrestrial laser scanner on the market.
