Hi BW:

The light source is built-in. It comes from below the slide, hence is
transmitted light. As a point light source, it will distinctly show the grain
(from which the image is made up). So you need a magnification like 30X which
will show enough image to be able to find the same spot on successive slides.
A poor alternative is a 30X pocket microscope with the built in light turned
off. One would view slides or negs a top a light box. The contrast on these
optics is very low and the light source isn't point, so the image is fuzzier
than I like.
Also try viewing through a 24 mm Zuiko reversed.
BTW, the 100-150 mm flat field Kodak projection lens is a rather high
performer for the money!
