In this measurement report of an injection needle the InfiniteFocusG5 plus with a Real3DRotationUnit is used as a measurement device. The new technology Vertical Focus Probing is an extension of the Focus-Variation technology and hence a pure optical measurement technology. It allows the measurement of vertical walls and micro holes directly without rotating the sample during the measurement. This significantly shortens the measuring time. The measurement task contains following parameter:

  • Concentricity of the top cone to the datum system
  • Concentricity of the middle cylinder to the datum system
  • Diameter of the middle cylinder and the datum system
  • Roundness of the middle cylinder and the datum system
