Condenser (optics)
Encyclopedia
A Condenser is an optical lens
which renders a divergent
beam from a point source into a parallel beam illuminating an object. It is an essential part of any imaging device, such as microscopes, slide projectors, and telescopes. The concept is applicable to all kind of radiation undergoing optical transformation, such as electrons in electron microscopy, neutron radiation and synchrotron radiation optics.

which renders a divergent
Beam divergence
The beam divergence of an electromagnetic beam is an angular measure of the increase in beam diameter or radius with distance from the optical aperture or antenna aperture from which the electromagnetic beam emerges. The term is relevant only in the "far field", away from any focus of the beam...
