I've tried using one of these for solder inspection some smt work 
(tqfp pads).  It didn't have enough field depth to be much use for 
that.  The bottom lens had to be practically sitting on the board to 
see anything.  You'd have to modify the bottom of the unit --it has 
an cowling that gets in the way.  For very flat subjects it might 
work.
