[Histonet] Cheap digital camera microscope adapters?

[Mikael Niku]

Hello!

I'm planning to purchase a set of digital cameras for our histology 
teaching laboratory, so that the students can do their histology work by 
taking microphotographs. Buying "real" microscope cameras would be too 
expensive as we need quite many (and our course microscopes don't have a 
camera tubus) so I'm thinking about fitting standard digital cameras in 
place of the eyepiece. The microscopes are good old Olympus CH2 ones and 
the cameras could be any affordable model.

If anyone can recommend a functional but affordable adapter, fitting to 
a functional but affordable consumer level digital camera, please tell!

With best regards,
