Component Specifications

Definition
The Target Body/Substrate is a critical reference component in measurement and calibration equipment, providing a stable, known surface or structure against which sensors, probes, or optical systems are aligned or calibrated. It ensures measurement accuracy by serving as a physical standard for zero-point reference, dimensional verification, or positional alignment in coordinate measuring machines (CMMs), vision systems, laser scanners, and other precision instruments.
Working Principle
The component operates as a passive reference standard. Its precisely known geometry, dimensions, and surface characteristics (flatness, parallelism, reflectivity) provide a fixed datum. Measurement systems compare sensor readings against this reference to detect deviations, calibrate offsets, or establish coordinate systems. In optical systems, it may include fiducial marks or patterns; in tactile systems, it provides contact surfaces with certified dimensions.
Materials
Typically made from materials with high dimensional stability, low thermal expansion, and wear resistance: granite (for flatness), ceramic (for hardness and stability), stainless steel (for durability), aluminum (for lightweight applications), or glass (for optical transparency). Surface coatings may include reflective layers, anti-reflective coatings, or hardened treatments.
Technical Parameters
  • Flatness ≤ 1 μm/m
  • Hardness ≥ 60 HRC for metallic types
  • Size Range 50 mm to 2000 mm (typical)
  • Surface Roughness Ra ≤ 0.1 μm
  • Dimensional Tolerance ± 0.005 mm
  • Thermal Expansion Coefficient ≤ 1.5 × 10^-6 /K
Standards
ISO 10360, ISO 25178, DIN 876, DIN EN ISO 14253

Frequently Asked Questions

What is the difference between a Target Body and a Substrate in this context?

In industrial metrology, 'Target Body' typically refers to a 3D reference object with known geometry (e.g., a sphere, cube), while 'Substrate' often denotes a flat plate or surface with fiducial marks. Both serve as calibration references, but the Target Body is used for volumetric calibration, and the Substrate for 2D planar alignment.

How often should a Target Body/Substrate be recalibrated?

Recalibration intervals depend on usage, material, and environmental conditions. For high-precision applications, annual recalibration against traceable standards (e.g., NIST) is recommended. Daily or weekly verification checks are advised for critical processes.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
