An optimal lens for this job is Linos Rodagon D 2x reversed, search ebay Rodagon D 2x, there are a lot used from Machine Vision systems, it may cost $200 used or less, see sold items
Today Rodagons are sold for industrial inspection cameras of linear sensor type, a similar application is Hasselblad X1 / X5 scanners also sporting a rody inside.
Other enlarger and taking lenses would also perform ok, better is reversed. But the Rodagon R and D are optimized for that magnification range, performing optimally and way beyond a human eye may see.
