Off-topic, but thought the Image-J community might be able to help.
I am considering purchasing of either a high-resolution medium format film
scanner (~4000dpi hardware optical res) or a high-resolution flatbed
scanner (>4000dpi hardware optical res)for scanning microscope slides -
rock thinsections to be precise. Some results of using such kit and which
have prompted my interest in using scanners, rather than a microscope
mounted camera, can be seen here:
http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artaug04/dwslidescan.htmlDoes anyone have any experience of using such scanners for this purpose
that they would be willing to pass on?
For my purposes i dont need magnifaction beyond the equivalent of a that
provided by a x10 microscope objective as the mineral grains in my rocks
samples are quite coarse. I need to obtain nice evenly illuminated sharp
images of the entire thinsection if possible.
On the above website, the results are shown of using a 35mm film scanner
2900dpi and although he has obtained good results for a thinsection, the
problem with using such a setup is that the orientation of the slid is
fixed. I wish to use plane polarised light with and without crossed
polars, so need to be able to place the slide in an arbitary orientation
relative to the polarisation axes, hence my idea is to use a medium format
film scanner or flatbed scanner with transparency tray either will give
more freedom.
Dedicated film scanners being considered for this purpose are Nikon
Supercoolscan 8000ED/9000ED, Microtek 120tf, Polaroid Sprintscan 120. all
4000dpi.
Flatbed scanner with transparency tray: Microtek Artixscan F1 (or M1 due
out next summer) 4800dpi supposedly
Thanks all, for your help.
