When evaluating laser scanning equipment for a project, one of the most important specifications to understand is the scanner's effective range. For the FARO Focus series, the industry-standard choice for precision 3D scanning, range capabilities directly influence what jobs you can take on, how you plan your scan setups, and the level of accuracy you can guarantee to clients.
FARO Focus Series Range Overview
The FARO Focus series operates across a range of 0.6 meters to 350 meters, making it one of the most versatile phase-based laser scanners available. That minimum distance of 0.6m matters just as much as the maximum: too close, and the scanner cannot register a return signal, which affects tight-space work like interior mechanical rooms or confined utility corridors.
At the top end, a 350-meter range opens up large-scale applications: outdoor industrial facilities, bridge inspections, open-pit surveying, and expansive commercial campuses. Understanding where your target falls within this range is the starting point for any scan plan.
Focus S vs. Focus Premium: How They Compare on Range
FARO offers two primary Focus variants, and range is one of the key differentiators between them.
FARO Focus S
The Focus S series (S70, S150, S350) is named partly for its range ceiling. The Focus S350 reaches the full 350-meter range, while the Focus S150 caps at 150 meters and the Focus S70 at 70 meters. The S series is widely used across AEC (architecture, engineering, and construction) and industrial inspection workflows. It performs reliably in both indoor and sheltered outdoor environments and hits a solid price-to-performance ratio for most professional teams.
FARO Focus Premium
The Focus Premium is designed for outdoor-heavy workflows where lighting variability is a real challenge. With a maximum range matching the S350 at 350 meters, the Premium differentiates itself through enhanced HDR imaging and improved performance under direct sunlight: conditions that can degrade phase-based scanners. For sites with extensive outdoor scanning requirements, the Premium's environmental robustness often justifies its higher cost over the base S series.
How Range Affects Project Planning
Choosing the right scanner range isn't just a spec-sheet exercise: it directly shapes your scan workflow and total scan count on any given project.
A longer-range scanner means fewer setups needed to cover large areas, which reduces field time and speeds up point cloud registration in post-processing. For example, scanning a 300-meter warehouse aisle with an S350 might require three setups; the same corridor with an S150 could require six or more.
At Laser Scan Chicago, project planning always starts with a range analysis: What is the largest open span we need to capture? Are there line-of-sight obstructions that would make maximum range irrelevant? What's the required accuracy at target distances? Answering these questions determines which Focus model is fielded, and how many scan positions will be needed.
Indoor vs. Outdoor Scanning Considerations
Indoor environments rarely push scanners to their range limits. Most interior spaces: even large ones like convention halls or multi-story atriums: top out well under 150 meters. In these cases, the Focus S150 or even S70 is often sufficient, and the priority shifts to speed, resolution settings, and ease of positioning around obstacles.
Outdoor scanning is where range becomes critical. Facades, infrastructure, topography, and open industrial sites frequently require 200–350 meter capture capability. Outdoor work also introduces ambient light interference, which is where the Focus Premium earns its keep through better signal discrimination in bright conditions.
Range vs. Accuracy: Understanding the Tradeoff
An important nuance: accuracy degrades with distance in phase-based scanners. The FARO Focus series specifies accuracy at defined distances (typically ±1mm at close-to-medium range), but noise levels increase as targets approach the scanner's maximum range. For projects requiring millimeter-level accuracy at 300+ meters, supplemental scan positions closer to the target: or switching to a long-range time-of-flight scanner: may be necessary.
Matching scanner range to the accuracy requirements of the deliverable is a core part of competent scan planning. Capturing at maximum range when moderate-range accuracy is sufficient adds unnecessary noise to the point cloud and increases cleanup time during processing.
Bottom Line
The FARO Focus series' 0.6–350m range makes it adaptable to a wide spectrum of scanning scenarios, but selecting the right model within that family: and planning scan positions accordingly: is what separates efficient fieldwork from costly re-scans. Understanding range, accuracy tradeoffs, and environmental factors is fundamental to professional 3D scanning practice.
