I agree, does an excellent job with Odonates. Also excellent for 'flat' flies such as syrphids and most tabanids, particularly
Chrysops. This calliphorid has a large somewhat rounded thorax making the fly very deep and thus could not get everything in focus.
It was scanned at 3600 ppi (pixels per inch). I simply removed the scanner lid; placed 4 blocks of wood on the glass plate of the scanner and placed a sheet of white card on the blocks. The blocks are 1 cm thick. The fly, of course, was placed upside down on the glass plate of the scanner. Alternatively one could support the scanner lid about 1 cm above the glass plate using blocks
