Convert a biological microscope into a wafer microscope?
Besides the need for reflected light attachments and different objectives, does a biological microscope have the working space for viewing wafers?
Since we're at it....
Is there a microscope body that can have any manner of stock attachments added to convert from, say, fluorescent light microscopy to Nomarsky to polarized to metalurgical to .......
Kind of like the contractor's white van of microscopes.

Most high-end microscopes do fulfill your requirements. A Leica DM6 for example. Just may cost a fortune.Rich Field wrote: ↑Tue May 10, 2022 6:00 am

If you want to buy used, a 50 years old Leitz Orthoplan or similar model offers everything you are asking for. Specific part may be hard to find.

Re: Convert a biological microscope into a wafer microscope?
Yeah, this is achievable with pretty much any major modular system. Wafers in particular are easy on wd since they're thin, though you may want a metallurgical stage to be able to easily translate them.
I've tried some nice metallurgical scopes. The olympus bh2 era setup is very good, as is the nikon optiphot (finite and infinite versions) The bausch and lomb balplan is weaker on field coverage but still very good. The basuch/cambridge/leica microzoom can be a good value though it is not very versatile or modular, and is a bit weak on resolution ane only decent in color correction. And more recent ones like the nikon eclipse series or a Mitutoyo finescope are excellent.

I may be mistaken, but I suspect the potential problem with adapting a ‘Biological’ microscope would its limited throat-depth.Scarodactyl wrote: ↑Tue May 10, 2022 7:57 amYeah, this is achievable with pretty much any major modular system.

What size of wafer are you considering, Rich Field ?

Re: Convert a biological microscope into a wafer microscope?
I'm not looking at "wafers" per se.... just happened to notice that a "wafer microscope" is a thing.
In short, it'd be cool to take some of that technology you find on e-bay, for pennies on the dollar, and throw it on a do-it-all chassis.
Throat depth... that looks like a useful term. I'd guess that biological (or clinical?) scopes have pretty small throat depths as a rule, which, I guess, makes sense. Might that include the Alphaphot and Optiphot line?

Re: Convert a biological microscope into a wafer microscope?
Thr alphaphot certainly has limitations on that front. The optiphot line includes dedicated wafer scopes as well as more biologically oriented stands. My personal epi microscope uses a nikon measurescope stand which gives a ton of room (and is incidentally massive). Not great for biological usage though.
If you want an SEM-like effect epi DIC can give it on flat surfaces. It is a lot cheaper to set up than transmitted DIC.

Re: Convert a biological microscope into a wafer microscope?
Keep in mind almost all industrial microscopes are augmented biological scopes with accommodation for illumination path and specimen manipulation. Then rebranded to reflect those differences

Re: Convert a biological microscope into a wafer microscope?
My Optiphot 66 wafer microscope has substantially stronger focus gears than e.g. conventional biological Optiphots.
Some Nikon wafer microscopes also came with diascopic condenser and illumination, so more nearly do-it-all.
