I think the economic motive has now been explained to you well
enough. But there's one point I didn't see addressed, unless Tsu did
it:
Quoted message said:The Naessens Diachromic Condenser, although it does not directly
enhance the resolution power of a light microscope, it does make very
small particles appear clearly as brilliant objects on a magenta
colored background (unique feature of the N.D.C.).
See that word "resolution" in the second like of the quoted material,
rb? That's the key word. "Resolution" in this case is the ability of
optical device, like a microscope, to do things like show a very tiny
object, *or* to allow you to see the distinction between two separate
(close-together) objects.
Not too many people own home microscopes, but you do see magnification
scams with telescopes sometimes. They'll try to sell you a scope with
gazillion-fold magnification, but a lens that's only a couple of
inches in diameter. Doesn't work -- you can magnify all you want, but
you'll just get a bigger version of the same image, you won't get more
detail. You need a bigger lens to get more detail.
With microscopy, you could probably enlarge the image as much as you
want, but it'd be like enlarging a picture from a magazine (the kind
that's made up of the little colored dots). Make it as big as you
want; you still won't get more detail, just bigger dots.
The reason the electron microscope is used is that you can get much
shorter wavelengths with electrons than with visible light, and you
can't see something smaller than the wavelength of the light you're
using; the light just cruises by such an object, unperturbed.
