Hi,

I am looking for a vendor for stereo viewers that I can use in our
teaching to 1st year Med students. We have some stero pictures of DNA
and of steroid receptors (from Nature and Science) and we want the
students to look at them withou getting a headache by using the
"squinting" method.

Can anybody help me?

Several years (> 10) ago I bought a Stereo Viewer ("designed by 
F.Voegtle") and a Reflecting Stereoscope ("design F.Voegtle /W. Schuss)
from VCH Verlagsgesellschaft, Weinheim, Germany. I found both 
instuments very useful.
I dont know wether they still sell this items, but you may have a look 
at their homepage  http://www.wiley-vch.de/
Hope that helps!

You could make anaglyphs - or reg green separations of the colours of 
the images.  Then all you would need are the stereo glasses with
one red and one green filter to see the stereo effect.  These are
very inexpensive and can be found easily.

Information on making such images can be found at:
http://dot.digibel.be/~guru/3dsoft.html

There are a variety of methods and software.  All do basically do the 
same thing: combine the red channel of one stereo image (of a stereo
pair) with the green and blue channel of the other.

Try looking up local forestry supply houses.  Stereo photography is a
common technique and one can usually find viewers at a variety of
prices.  I use Ben Meadows company in the US.

Omni Resources ( http://www.omnimap.com/ ) sells several models
of stereo viewers from inexpensive plastic models to top of the
line foresters' stereoscopes.  If you plan to do quite a bit of
viewing you should consider getting a pair with glass lenses.
The plastic ones are OK for introductory classroom use but will
probably strain the eyes after prolonged use.
