Hi all,
I've been reading about biconvex lenses, drawing ray diagrams and real/virtual images. I'm now trying to translate this into how an image is formed in a compound infinity optics microscope. And this has raised some questions:
-In an infinity optical system the object is placed at a distance (F) the focal point of the lens on the object side and therefore the lens converts the refracting rays to parallel ray bundles on the image side?
-Because the object is always placed at the focal point an image is not formed by the objective?
-The role of the tube lens is to converge the parallel rays traveling in line with the principal axis?
-The point at which the rays converge on passing through the tube lens is the focal point of the tube lens on the image side, the intermediate image plane?
-If the light travels in parallel lines between the objective and tube lens, is the light therefore collimated? And the objective is basically a collimator?
Really I'm just wondering if my understanding on the above is correct? Ray diagrams tend to over-simplify things.
Thanks for the help!
