Hello Gangโจโจ I found few days ago a beautiful Leitz Laborlux K (with fluorescence) at a price no one could refuseโฆโจโจ ๐ So hereโs Iโam with the beast, but I do not enjoy that much the small bino head and quite narrow view field. My question is : which better trio/bino head (with 30 min WF ocular if p...

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 .

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...

Thanks you both of you Scarodactyl and Pete. Iโm asking that as I received a beautifully Apo objective for Axiomat. So the thread part on the objective is not on the top but 1/3 down, and there is a huge upper protubing part that needs to be covered by an extension tube. I did something with tape + ...

Immersion objective with live sample
Hello Gang,
Iโd 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 pondโs water to avoid using cover (as there is an option for W Imm with no cover) ? Or do I risk to spoil it (sand...) ?
Thanks you all for your inputs...

Which Occular x12.5 for an Axioplan/Axiophot Zeiss ?
Hello everyone,
Iโd 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) . And is there someone here that had a pair to sell ?
Thanks for your advice .

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 ?
