WANT TO PERFORM LOW MAGNIFICATION OBSERVATIONS WITH A COAXIAL ILLUMINATED USB MICROSCOPE

 

Our Z500CS coaxial illumination USB microscope comes with a 1.5x auxiliary lens as standard.

 

This time, we tried to observe the metal parts of the USB memory.

 

 

 

Observe with 1.5x secondary lens (basic specifications)   Focal length, magnification and field of view are: ・Focal length: 52mm ・Visibility range(at 65x): 5.2mmx3.9mm ・Visibility range(at 390x): 0.8mmx0 .6mm

 

Seen like this at 65x   Seen like this at 390x

 

 

If you want to observe at low magnification, remove this 1.5x auxiliary lens to reduce magnification.

 

Remove the 1.5x secondary lens. Focal length, magnification and field of view at this time are: ・Focal length: 95mm ・Visibility range (at 45x): 8.0mmx6.0mm ・Visibility range(at 270x): 1.2mmx0.9mm

 

Seen like this at 45x   Seen like this at 270x

 

 

If you want to observe at even lower magnification, attach the 0.75x auxiliary lens to reduce the magnification.

 

Attach the 0.75x auxiliary lens At this point, the focal length, magnification, and field of view are: ・Focal length: 113mm ・Visibility range (at 35x): 11.3mmx8.5mm ・Visibility range (at 210x): 1.7mmx1.2mm

 

Seen like this at 35x   Seen like this at 210x

In this way, the minimum magnification of 35x (0.75x) cannot be used because the coaxial illumination becomes unbalanced.

Therefore, the lowest practical magnification is to remove the standard 1.5x auxiliary lens and observe at a minimum 45x magnification.
