Carlson Scan2K

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.

Key Features

• Scanning range up to 2000m
• Data collection rates up to 500,000 points per second
• Hot-Swap Lithium-Ion Batteries
• Sunlight-visible color touch screen interface
• On-board L1 GNSS receiver
• On-board digital cameras
• Optional external camera and external GNSS mount
• Configurable for tripod or mobile deployment

Beyond its impressive 2,000 meter range, the Scan2K also has short- and medium-range modes, as well as the capability to record over 500,000 points per second, all within the chosen scanning target window. Additionally, each laser pulse from the Scan2K records up to four returns, providing the capability to record the first return for a blocking object (such as a leaf) as well as the last return for an object behind it (such as a wall), and the versatility to exclude one or the other.

The Carlson Scan2K comes bundled with ATLAScan software, a powerful yet simple solution for registering the point cloud, as well as Carlson Point Cloud Advanced for feature extraction into Carlson’s suite of CAD office products.

The Scan2K comes ready to be equipped with an additional external camera, an external GNSS receiver, or for mobile operation.

Whether on a tripod, a vehicle, or another moving platform, the outstanding performance offered by the Scan2K easily makes it the most versatile terrestrial laser scanner on the market.
