Calibration Target

Precision reference artifact for calibrating 3D pattern scanners to ensure measurement accuracy and repeatability.

Component Specifications

Definition
A calibration target is a precisely manufactured physical artifact with known dimensional properties, used to calibrate and verify the accuracy of 3D pattern scanners. It establishes a reference coordinate system, corrects optical distortions, and validates scanner performance against traceable standards.
Working Principle
The calibration target provides known geometric features (points, lines, patterns) that the scanner captures. Software compares the scanned data to the target's certified dimensions, calculating correction factors for lens distortion, scaling errors, and coordinate alignment to ensure measurement traceability.
Materials
Typically made from stable materials with low thermal expansion: ceramic (alumina, zirconia), glass, or anodized aluminum. Surface features may include chrome plating or laser-etched patterns on a contrasting background.
Technical Parameters
  • Flatness ≤1 μm/100 mm
  • Size Range 50 mm to 500 mm
  • Traceability NIST/PTB certified
  • Feature Types Dot arrays, grid patterns, concentric circles, step heights
  • Accuracy Grade ±0.5 μm to ±10 μm
  • Thermal Expansion <1.5 ppm/°C
Standards
ISO 10360, ISO 25178, DIN 32877

Frequently Asked Questions

How often should a 3D scanner calibration target be used?

Calibration should be performed daily or before critical measurements, after environmental changes, or following scanner maintenance to ensure consistent accuracy.

Can one calibration target work with different scanner models?

Targets are often model-specific due to varying field-of-view and software algorithms, though some universal targets exist with adjustable parameters.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
