This is description of this part:
This is a double objective lens, meaning it offers two possible magnifications. With the second lens extended, it has a magnification of 3.5x, and with the second lens attached, it has a magnification of 10x. The description on the objective lens says "35 u. 100x," meaning "35x and 100x," as this indicates the magnification of the entire microscope with the default 10x eyepiece.
