Dipping Cone

#1 Post by sreynolds » Sat Mar 25, 2023 11:51 pm

This came with an objective I bought on Ebay as an 'extra'. The objective is a regular Nikon CFN 20x 0.50 160/.17. Can anybody tell me what it is and what it is used for? Thanks.

Nikon made a series of finite water immersion objectives. This screws onto the end of the 20x version as a replaceable item. Those objectives look a bit like Nikon's "CFN" series with the three large knurled rings up top; but this part at the working end.

Pete - Thanks. I have no use for it, so I will post it on the exchange forum - if someone wants it, send me a PM and I will send it for mailing cost.

Looks like the top lens for the condenser but it's got no measurements with it.

FWIW, Michael, that image is the same as the ones I have (but modified for Hoffman contrast). If you have one, the cone should fit. These are dipping objectives, not meant for a drop of water over a coverslip (more like dipping into a Petri dish for electrophysiology, etc. applications).

Sure looks like the part, I have a 20x .5 CFN. Never wished it could be dipped.
