Optimet's MK10 with a 25 mm lens was used in the application of key scanning. The main industrial
application during the scanning is related to the scanning of the key's slots. Highly accurate results were
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
Key scanning using Optimet's MK10 ConoProbe 25 mm lens.
- Measurement rate: 9 kHz
- X‐step: 20 µm
- Y‐step: 40 µm
- Laser power level: 63
Total and SNR filters were applied on the RAW data and after that it was export to Mountains Map software for analysis.
3. Results and Observations
The key was placed so that only the slots were within the working range (fig.1).
Note – scan was done in Y direction.
