Carl, There is a company in Houston, Texas - Meyer Instruments - that sells scanners that are specifically designed for microscope slides (e.g., https://www.meyerinst.com/pathscan-enabler-5/). I have never used their products (we have an older Nikon scanner) and don’t want to act as their sales representative. For example, I don’t know how their scanners compare to others in quality vs. price. However, I do know that this company has been is business for about 30 years and have sold microscopes to geology departments. If you do look into this option, I would be interested in your opinion.

I know of the Nikon Super Coolscan5000 but it's not in production anymore. Any recommendations? Cheers Carl ____________________________________________ Carl Guilmette, B.Eng. PhD.
