Size of square head on Reichert Zetopan phase carousel adjustment screws

#1 Post by brettpim » Wed Oct 05, 2022 11:26 pm

I have phase contrast and an IK contrast condenser carousel for a Reichert Zetopan. For the phase rings (and correspondingly on the IK condenser) there are tiny square headed screws to adjust the centring. For the information of the community the square is 1.12mm square and it can be manipulated with an English Square size 2, Swiss Square size 9 or Indian Square size 9 pocket watch key if its shaft is suitably thin; my key, which works, has a 2.46mm diameter.

Thanks for posting this, Brett

I have no immediate need for the information, but I might get lucky one day !

We should probably all be sharing more of such useful details.

On this set of pocket watch keys I just bought, the best fit is the #10

Hello Brett,
thank you very much for the informations. I was searching exactly for this size of the mentioned square screw in the condenser.
I also got both condenser types, PH and IK. Do you know what type of adjustment the screws do when turning them for the wollaston prisms holder in the IK condenser? Do they only center the prism or also rotate it?

cesarius,

I have not explored the IK condenser yet, other than verifying that the watch key fits, so I am not sure, sorry. Now that I can manipulate the screws, I will be starting to teach myself phase first and then move on to IK. Do you have any tips for learning either of these techniques?

thanks
brett
