Screw Scan  

Executive Summary

Optimet's ConoProbe MK10 was used in the application of screw scanning. The tests were performed to demonstrate measurement capability. Two scans were made, one using talc powder and one without talc powder.

1. Optimet's Advantages over Other Technologies:

1. Unique collinear technology
2. Capability to measure sharp angles in minimum clearance  
3. High lateral resolution.
4. High sampling rate with no need for averaging

2. Application Description

Plastic sample scanning using Optimet's Conoline with a 25 mm lens. A screw was measured by the ConoProbe MK10 with 25 mm high definition focal lenses. Test settings:
  • Measurement rate: 9 kHz
  • X‐step: 4.8 µm
  • Y‐step: 10 µm
  • Laser power: 11
