plan or neofluar
plan or neofluar
is there a list / ranking of zeiss objectives somewhere?
which one is (better)?
which one is (better)?
Re: plan or neofluar
Achromat
Planachromat
NEOFLUAR
Plan-NEOFLUAR
Apochromat
Planapochromat
If it just says Plan then it is an Planachromat
Planachromat
NEOFLUAR
Plan-NEOFLUAR
Apochromat
Planapochromat
If it just says Plan then it is an Planachromat

Re: plan or neofluar
thanks...pretty much what i thought...the neo's came on a scope i bought recently...think i'll keep those on my main scope now. move the other two..10 and 40x down to my secondary scope...they seam very close image wise but hey..the optics are bigger so more light passage is more /better?
Re: plan or neofluar
What you want to look at (apart from the colour correction) is the NA (Numerical Aperture)
In the Planarchromat is 0,22. The NEOFLUAR is 0,30
Higher is better.

Re: plan or neofluar
Well resolution-wise. Seems like you would be almost halving your depth of field though, if that's important.

Re: plan or neofluar
Also it is without the plan corrections, right? So the plan objective would be superior if your purpose was to take a black and white photograph with a large depth of field.

Re: plan or neofluar
Neofluars are supposed to be quite plan, at least that is what Zeiss literature hints, although they do not provide a quantitative figure of merit.BramHuntingNematodes wrote: ↑Tue Sep 01, 2020 2:33 pmAlso it is without the plan corrections, right?

Re: plan or neofluar
they can't be too plan how else you gonna market the plan neofluars

Re: plan or neofluar
Neofluars preceded plan-Neofluars. Plan-Neofluars (for those old 160mm TL microscopes) are not available for all magnifications.BramHuntingNematodes wrote: ↑Tue Sep 01, 2020 4:30 pmthey can't be too plan how else you gonna market the plan neofluars

Re: plan or neofluar
they are pretty close when it comes to focusing the middle vs edges...for pics i can stack em

Re: plan or neofluar
If you are going to resort to stacking, then the depth of field argument weakens too

Re: plan or neofluar
I am attaching a related page from a dated Zeiss Manual which should be helpful a bit more over the good replies you got

Re: plan or neofluar
so is one on left just a repackaged version of itself?
