Re: what camera lens to use for Parphocal setup?

Thanks Sarodactyl, I guess that a 0.5x or 0.75x relay lens will be closer to a 40mm lens am I correct?



Also if you have this phototubes set, could you please tell me the length of the long tube with the two screws?
I want to make a 3d printable version of the set.

Thanks

Re: what camera lens to use for Parphocal setup?

I have seen a Leitz phototube which uses a 0.32x relay lens. So will a setup with camera without lens+0,32x relay lens+10x eyepiece be equivalent to
a Camera with 40mm+10x eyepiece?
What about using an eyepiece with a widere field of view like a GF 10x/20?

Thanks.

Question about Phototube and reduction lenses.

Hello
I am trying to build a Leitz phototube with different parts (for a Laborlux 12).
I can't find de Leitz 162226 which is a 0.32x barlow lens I belive.
My question is, if instead of using a 10x ocular in the phototube I use a 6.3x lens
will it be equivalent to using the 0.33x?
Thanks

Basis question about infinite objectives compatibility

Hello, For what I read so far I was sure that one can not combine Infinite objective with standard 160 objectives, but I have seen several microscopes on ebay which are sold with a mixture of lenses. Such as this one combining expensive olympus infinite with some Leitz plan https://www.ebay.com/itm/...

Thanks Einman I think i got it close enough to your measurements. The only thing left is the thickness of the slider and the thickness of the depression where you place the annuli.
