📏

Enter measurement distance and instrument class to calculate total error budget.

🔬 Technology Comparison

ToF: 0.05–200 m, ±1–3 mm, best for long range
Phase-Shift: 0.05–100 m, ±0.5–2 mm, fast & accurate
Triangulation: 0.05–10 m, ±0.1–1 mm, highest precision

⚠️ Error Factors

Base accuracy: instrument specification (±mm)
Distance factor: ~0.01–0.05 mm per meter
Target reflectivity: dark surfaces add 0.5–2 mm
Ambient light: bright sunlight adds 1–3 mm
Temperature: ~0.01 mm/°C deviation

📋 Typical Applications

Construction layout: ±2–5 mm acceptable
Interior design / room measurement: ±1–3 mm
Industrial alignment: ±0.5–1 mm required
Surveying / mapping: ±1–2 mm typical
Warehouse / logistics: ±5–10 mm acceptable
