Why are convegent lens used for amplification?


I have seen today a video on electron microscopy and the way TEM was explained, with a point light passing through lens, got me asking: After making the rays of light parallel, they go through a lens to amplify the image. My question is, this lens converge the light rather than diverging them. The rays converge onto a single point, and then diverge. Is this method of amplification less prone to constructions error on the lens, or more precise in general?

You need to think about it from the other direction…the lens converges light onto the object, but that’s not the direction we see things…we see light/electrons coming *from* the object. So as they bounce back from the object and back through the lens they *diverge* (get farther apart), making the image appear physically larger than the object.
