Re: Microscope for moss/plants

That budget will get you a very nice brightfield scope with trinocular head. Actually connecting the camera to the head can sometimes be a bit of a DIY project, but it doesn’t need to be expensive, necessarily, and that can be a future project. You will need to decide wether to buy new or used. A ne...

ID this stereoscope?

I was wondering if somebody could tell me anything about this stereo microscope I stumbled across. The only name to be found is “Bioscope” on the eyepieces. There is a “Japan” sticker on the bottom (no “made in” ... maybe they are a just a fan of the country :D ) I thought it might be a Chinese clon...

Re: Adaptor for DSLR camera

Thank you for your reply! I understand that it's going to be awkward trying to use my DSLR without a trinocular head, but I really want to give it a go. Can you explain what you mean by a dedicated photo head? Presumably this is something that is an integrated part of a microscope? I meant a monocu...

Re: Fixed Köhler

Every design has compromises; cost, size, etc. If you taught a few biology classes every day, this compromise means you don't have to check every single microscope after every single class to see who fiddled with what. Then it might seem like a very good compromise. Not every setting requires that l...

Re: Polarizing filters

I have one Tiffen and one Hoya that together offer excellent extinction. Those are good mid-priced brands. The cheap ones that I got bundled with lenses aren't nearly as good. The Amazon film I got falls somewhere in between.

Can you add a little information about the camera? I did a quick search for that make and model but couldn't find an exact match.

Re: Roughly when did microscope manufacturers stop making their own glass?

The other resource that would have been critical is fuel for the furnaces. A century ago, that meant coal; something in abundance around the Great Lakes thanks to steel production.

Thanks. I'll lok for sheets. Those filters are expensive and too big.
You can get them for peanuts used, though. Just have to keep your eyes open. If you have a local camera shop they probably have a drawer full of old used ones. The small ones aren’t any good for modern lenses.

You buy polarizer sheets on Amazon or use camera filters. (Circular polarizers need to be oriented correctly to work. Linear can have either side up.)

I don’t speak Olympus, I guess. In Reichert-speak “Neo” means nearly or almost. The NeoPlan objectives are close to plan, but slot in under the Plan Achros.

Re: Where Can I Find Ciliates without Any Creeks or Ponds?

I’ve found a birdbath, left to its own devices other than topping off, develops quite a rich ecosystem. Large surface area catches lots of airborn “stuff” and visitation by a variety of critters that bring many hitchhikers.

Re: Adaptor for DSLR camera

The best way to connect a DSLR depends more on the microscope than the camera. Typically, it is preferred to avoid eye-piece adapters for DSLR's due the size and weight.

I considered that, but I paid $24 + $40 shipping in an auction with other bidders so unless that was an unusually good deal (not sure since I had been mostly watching series 400 stuff) it seems like the stand/objectives alone are probably not valuable enough to be worth the trouble reselling on eBa...

Hi Aaron, I think the combination of computer and optics has lots of future. Especially in the form of an open source project where many people contribute to the further development.

Re: AO/Reichert One-Fifty vs. Reichert-Jung Series 150 differences and head compatibility

Does the trinoc produce a well corrected image on the 410? (through one eypiece ... I know you said there was some issue there) If so, I think that answered the question. If the 150 were from an educational venue (likely) they may have been ordered that way simply to hit their budget. Students can l...

I have not been watching series 10 stuff, but that makes sense. Of course, it is also the dangerous type of reasoning that already has me owning more microscopes than I logically need...

You could also consider abandoning the older objectives, instead using some spare 45mm parfocal objectives and 410 head it came with. (depending, of course, on how much extra clearance there is under the stage) Given the price of nice series 10 stands right now, it seems hard to justify putting too ...
