Our coaxial illumination USB microscope, model Z500CS, comes standard with a 1.5x auxiliary lens.
This time, I observed the metal part of a USB memory stick.

Observation using a 1.5x auxiliary lens (basic specification)
The focal length, magnification, and field of view at this time are as follows: |
|
|
When observing at low magnification, removing this 1.5x auxiliary lens will reduce the magnification.
 |
Remove the 1.5x auxiliary lens.
The focal length, magnification, and field of view at this time are as follows: |
|
|
If you wish to observe at an even lower magnification, attaching a 0.75x auxiliary lens will further reduce the magnification.
 |
Attach the 0.75x auxiliary lens.
The focal length, magnification, and field of view at this time are as follows: |
|
|
At the lowest magnification of 35x with the 0.75x auxiliary lens, the coaxial illumination becomes unbalanced and cannot be used.
Therefore, it is practical to observe at the lowest feasible magnification of 45x by removing the standard 1.5x auxiliary lens.
