I've never had problems with canon efcs, it is vibration free during shooting.

They are largely Chinese but they also have a relationship with Meiji and sell some of their Japanese made microscopes under their own brand.

Re: Do I need another objective?

I'd watch for a favorable auction, not a buy it now. I got mine for 450, this one is starting at 600 but it's also VC (a little better than apo) https://www.ebay.com/itm/315246893929

Re: Do I need another objective?

Using my planapo 60x/1.40 on my e800 was a bit disappointing since it has a dry condenser which throttles resolution. The oil condenser is very rare, I have never seen one for sale. I get better results using it with epi illumination/epi DIC on my other scope since it acts as its own high na oil con...

Re: Leica Reichert Jung Polyvar (models)

Yes but the f.N. only matches the real or viewed ield with a 10X eyepiece.because they are the default and the system's logic is based entirely on 10X eyepieces. It seems to me that the confusion is arising from thinking of it this way, even if there's nothing technically wrong with it. A 1x object...

Re: Leica Reichert Jung Polyvar (models)

Field number is based on a hypothetical 1x objective, not a 10x eyepiece. It's just a question what the diameter of the imaged field would be with a 1x objective, regardless of how large it looks to the eye.

Re: Do I need another objective?

First things first, get a cheap 20x/0.75 apo. Make sure it is the labeled one. It's an incredible objective and absurdly cheap because they were widely used in gene sequencers. The 20x fluor slider works pretty well with it. Edit: currently the price is a bit higher, the last glut was a while back. ...

Re: GF Planachromat infinity optics for Jenamed microscope

I think the 1x also required a special upper lens like some Nikon cfi60s did a generation or two ago (1x macro).

Re: Wild M8 vs Wild MZ3

Don't get an M3b imo unless it is quite cheap. Being a step mag isn't bad but only having 3 settings is a bit of a bummer vs 5 on the m3c or continuous on the m3z, the C is a basically strictly better with no optical downside, the m3z is somewhat nicer to use even if the zoom probably has some optic...

B&L made at least one DIC system, epi DIC for the balplan. A rare but impressive piece of equipment. The AO epi is also pretty exceptional.

Re: Reichert U.S.A. and Leica. Why the undercorrection?

I understand why this was necessary in the 60s and earlier, but I do find it odd that Nikon was able to manage so well without additional corrections in the 80s, followed by Olympus and Mitutoyo, while Leica and Zeiss cling to it still. I kind of assume Leica and Zeiss should have the best engineers...

Re: what objectives have you tried on wild M8

65mm thread objectives have an added 1.25x magnification on m50/m60 systems like the M8, so it would act as a ~0.78x. Leica plan apo stereo objectives are quite nice.

Re: Polylite SC endusers(?)

That .32X fractional lens is to compensate for the tube length and reduce unwanted alterations in W.D. It isn't needed if the tube length is kept to something close to the reference length. My understanding is thst, as designed, a viewing or afocal photo eyepiece projects an image at infinity focus...

Re: Polylite SC endusers(?)

A wild eyepiece isn't going to do what you need it to corrections-wise, they are basically neutral (and their field coverage is awful, 21mm fn). But that general setup with a widefield Riechert eyepiece and a shorter focal length lens subbed in for the 0.32x lens (maybe 40mm) could give quite good r...

It is typical for these highly specialized units that were sold to industry rather than academic labs. The photo tube likely has correcting optics sin...

These are from the 80s from what I understand, pretty late in the Jena lineup. They come up pretty frequently on eBay. I have not tried them but reviews have been quite good.

Re: GF Planachromat infinity optics for Jenamed microscope

-A means it is internally corrected (ie part of the CF250 system, using a 250mm focal length tube length neutral tube lens, no eyepiece corrections).
-This one is meant for reflected light )but you could get away with transmitted light.)
-I believe they have a 25mm thread.

Re: has anyone used Leica S-APO 10x objective?

For a bit there they were branding fluorites as s-apo (semi apo). Given the lack of full internal correction on top of that I wouldn't consider it a very appealing target.
