You can change the magnification by attaching it to the front (object side) of the main lens. It is also possible to change WD (working distance).

You can see that the field of view has expanded by attaching 0.5 times the auxiliary lens.
* When using a 0.5 times auxiliary lens, the working distance changes and the distance from the lighting to the object increases. Thus, it is necessary to change the position of the lighting using the LED angle.
