From time to time, we receive questions like this.
Q. I want to use measurement software to measure dimensions while observing at an angle.

A. Of course, it can be used without any problem, but there are some precautions to be taken.
Vertical and oblique observations at the same magnification
The aspect ratio changes when observed from an angle.
(Below is a glass scale of 0.5mm x 0.5mm)
Therefore, the vertical calibration value cannot be used as it is, even for the same magnification observation.
When measuring with oblique observation, it is necessary to apply calibration under those conditions.
conclusion
In order to measure accurately with oblique observation, it is necessary to calibrate the microscope with it tilted at an oblique angle.
However, if the microscope is tilted in two axes (not only to the left or right, but also to the front or back), calibration should be performed with both axes considered.
