Hi Matthew,
The loupe I borrowed for these tests is rated at 5X power and has two lens elements separated by a small ring spacer in the column. It is used by fingerprint examiners and can be found on the Sirchie website. As I recall it lists for $79. I also have a small plastic one by Bausch and Lomb that is foldable and will run some tests on it when time permits.
Others have used the Raynox DCR-250 as a supplemental close-up lens with good macro results. The only other supplemental lenses I have are three Vivitar +1,+2, and +3 diopters but the quality of the images is not as good as with the loupe.
