Electron Microscope.
The 40x objective lens is one of the (usually) 3 objective lenses. It magnifies the image by 40x (hence the name). However, the image you view doesn't have a magnification of 40. There is the ocular lens, which typically is 5x or 10x, in addition to the objective lens.
You are describing a compound light microscope. It magnifies objects through a combination of lenses (ocular and objective) and has a stage where the specimen is placed for viewing.
Another name for the light microscope is the optical microscope.
The most powerful microscope is currently the electron microscope, specifically the transmission electron microscope (TEM) and scanning electron microscope (SEM). These microscopes use beams of electrons to achieve magnifications up to millions of times, allowing for incredibly detailed imaging of samples at the atomic level.
What was the name of the first microscope?
A lower power lens tells its name in the name. It is a lens in a microscope that has the lowest power, or only magnifies the object you are looking at a little.

The eyepiece of a microscope is used to magnify and focus the image of the specimen that is being viewed through the objective lenses. It allows the viewer to see a larger and clearer image of the specimen. The eyepiece typically provides additional magnification to the image produced by the objective lenses.
The another name for a compound microscope is a light microscope, as it uses light to illuminate the specimen being observed.
