Re: Considering upgrade of stereozoom 'scope

Hi 75' - and thanks! That's a very useful post indeed which, even if it isn't entirely successful with my relatively limited AmScope will certainly be handy as and when I 'go up a notch' in the stereozoom stakes. Nice to see something concisely and precisely written too; makes a change from the ubiq...

Re: Considering upgrade of stereozoom 'scope

Maybe this is a dumb question, but did you do the initial setup of eyepieces for parfocality? It might help anyway. Wilds are definitely excellent. Definitely not a dumb question, I've lost count of how many times I've overlooked the basic or even the downright obvious during microscopy, from day o...

Argghhh.... sounds perfect, the shared path is good presumably for stills where vieo-logging isn't needed!

Re: Considering upgrade of stereozoom 'scope

Yes, they do seem to have a consistently excellent reputation. I must however have the ability to use both eyepieces AND the camera simultaneously, preferably switchable too. Does yours have this capability?

Re: Considering upgrade of stereozoom 'scope

UPDATE, All's now well and operating as expected considering extra light-split of the simul-focal system. What happened? - considering the last poster's reference to the glassware itself I inspected and cleaned the slightly grubby lenses of both light paths, i.e. their bottom lenses, nearest to spec...

Re: Considering upgrade of stereozoom 'scope

Hmm, I have made quite a good improvement by removing the 4 layers of plastic 'frosted-glass effect' film that I had over the LED light-ring's LEDs. I tried this makeshift diffuser when experiencing bad reflections with specimens not quite covered with water (in a petri dish or similar). Later I rea...

Re: Considering upgrade of stereozoom 'scope

Hi all, I ended-up buying a "simul-focal" version of the one I have. It's very similar indeed, although the body is slightly smaller (in width anyway). Fitting is the same and I dropped it straight into my current stand - perfect fit. It came with a rather nice boom-stand onto which I set my old non...

I think it goes between the specimen and the analyser. On my BX50 it sits under the analyser and may be slid in/out.

What's your budget range? There are some good used CMO options but it depends on how much you want to shell out.

Considering upgrade of stereozoom 'scope

Hi all, I'm really quite fed-up with the tragic images coming through the trinocular photo-port of my generic (badged as Amscope) trinocular zoom stereo 'scope. It's of the type where the left eyepiece is given-over to the photo light-path with the pull of a pell/push bar. Also it's the usual Greeno...

Thanks John, those threads were great! Fantastic detail! It's nice to see the kind of results you can get with hand-sectioning.

They certainly do add to hand sections, see here
