condenser insert set

#1 Post by iconoclastica » Sun Aug 23, 2020 10:11 am

Has anyone tried one of these https://www.ebay.co.uk/sch/bauras/m.htm ... 7675.l2562 ?

I have always read these modifiers ought to sit near the diapragm, but in this contraption they are much lower. Isn't the position perhaps that important?

These are INSERTS into the condenser and close to the diaphragm. I’m pretty please with my set.

What type of condenser are you using? On my 0.90 achromat the diaphragm resides c. 30mm above the bottom plate.

Olympus BH2 with standard Abbe condenser or Phase condenser.

Nikon Achr 0.90 is not the best candidate to use with DF inserts, because of the internal design (I fixed your drawing a little bit). Internal "opening" (green) does not allow to go closer to the aperture .
Of course, for the DIY purpose, opening could be widened, but it is kind a aggressive measure. It is doable, but not sure how many user are ready to make this kind of surgery on the own condenser. Abbe 1.25 are pretty cheap

I bought a set for an Olympus BH2 from the same guy and I'm quite happy.

That explains it. Also, I gather there are two different models of the achr 0.90 about, for my drawing was exact too (at least on the outside).
I will look for another condenser for this purpose, that seems to be the best way to go indeed.

thanks,

Wim

It is real, not the perspective. Mine is between 7 and 7.5mm deep:
