Measurement Principle: White Light Interferometer

KORAD^3D is a compact measuring head based on the white light interferometry measurement principle. It compares the path length of the light reflected or scattered by the object surface with a reference path length. In this patented measurement process, the measuring head scans the object while moving in the z-direction.
The results is a 'depth image' of the object with a very low measurement uncertainty. It combines the advantages of common tactile sensors with the benefits of optical sensors: high measurement accuracy and non-contact, high-speed scanning with a high data rate.

Technische Details:
- Lateral measurement fields from 2 x 2 mm² up to 50 x 50 mm²
- Lateral resolutions from 5 µm up to 100 µm
- Longitudinal measurement range upt to 100 mm
- Longitudinal measurement uncertainty:
  - for optically rough surfaces: typically 1 µm (object roughness)
  - for optically smooth surfaces: up to 5 nm
- Measurement speed up to 100 µm/s (longitudinal)
- Measurement times: possible clock speeds of < 1.5 seconds

 
Measurement Examples

Shadowing is avoided through coaxial illumination. Low lying surfaces in drill holes can be measured without any difficulty. The illustration shows an example of the measurement of various tapered surfaces in a borehole approximately 10 mm deep. By a similar method, tapered surfaces are measured in a 40 mm deep borehole with a diameter of 3 mm.
