Re: Objective with lower magnification than it should

Yes @apochronaut I have an optovar. So with an eyepiece x10 and the Optovar x2,5, I might be around the limit of the Apo dry objective NA 0.95 ๐Ÿ‘๐Ÿป๐Ÿ˜‡.

Re: Objective with lower magnification than it should

Yes it is far higher than my 25x and a bit lower than the 40x.

Do you think something can be done ? Extension on the objective or at the eyepiece level ?

Re: Objective with lower magnification than it should

@Apochronaut, thanks you for these historical information. It seems now that the objective would de more efficient if the tube was a little smaller of 20 mn (the protubing part above the tread) @Scarodactyl, by the way it is impressive that it lower the magnification of around 25% Instead of a 50x/0...

Objective with lower magnification than it should

Hello all, I adapted a Zeiss 50x/0.95 dry objective from an Axiomat Zeiss (infinite) to my Axioplan (infinite). It works perfectly but... obviously the magnification I obtain is lower than the one I have with the 40x/0.75 objective ! Is there an explanation or is my 50x damaged ? Contrast, image and...

Immersion objective with live sample

Hello Gang,

Iโ€™d like to know if it would be wise or dumb to use my neoFluar x25/0.80 Multi Imm Zeiss directly in thin layer of pondโ€™s water to avoid using cover (as there is an option for W Imm with no cover) ? Or do I risk to spoil it (sand...) ?

Which Occular x12.5 for an Axioplan/Axiophot Zeiss ?

Hello everyone,

Iโ€™d like to improve my Axioplan Zeiss with new oculars in 12,5x (or 15x) with a field as wide as possible ( and glasses compatible).

Which ones would you suggest to me (to look for on the Net) ๐Ÿ˜‰. And is there someone here that had a pair to sell ?

Thanks for your advice ๐Ÿ‘๐Ÿป.

Very interesting piece of information @Viktor. Does it leans that I do not need DIC Neofluar to achieve DIC (as long as the condenser and the prism bounty fit) ?

Hello gang,

I have a newbie question :
Some of my objectives are Pol ones. When I use an adequate DIC prism (and adequate condenser) with these polarized objectives it seems to work quite well as a DIC set up. Does I do/have something wrong ?
