What is a NEWPORT Table?
The Newport table is a an optical table designed to hold laser lens and mirrors. Some customers use them as similar to a granite surface used to measure tube shapes. |

Scanning Example
The image on right shows an example of scanning a tube on a Newport table. | |
Potential For Outliers At Normal Relfective Surfaces
The Impact on Cylinder Calculations
If VTube uses these outliers to calculate the diameter, then often the cylinder fit math will fail to find a centerline - and VTube will ask you to remeasure the straight where the problem is occuring. | |
