Illumination systems cover a wide range of applications including
fiber illuminators, projectors, and lithography systems. The design
of an illumination system often requires balancing the tradeoff
between providing uniformity, maximizing the collection efficiency
from the source, and minimizing the size of the optical package.
These tradeoffs will be examined for systems using lightpipes, lens
arrays, faceted optics, and integrating spheres through a
combination of computer simulations, hardware demonstrations and
discussions.
