AO phase contrast condenser for series 2 and 4 and 20x Dark M objective

Post by zzffnn »

I have, for sale, an American Optical phase contrast condenser taken from a series 4 scope, that looks exactly the same as this eBay listing (minus "770" label):

https://www.ebay.com/itm/255161027696?h ... SwNwhhWQB1

10, 20, 43, 97 annulus, "o" iris slot, everything works perfectly. I tested it on a series 4 scope, along with an AO 20x Dark M phase objective, which is also for sale.

Same price as that eBay listing (not mine).

I may trade for a darkfield condenser for series 2/4 scope, 20x AO bright field objective, ~97x AO bright field objective with funnel stop and a second ~97x bright field objective without funnel stop. Plus or minus cash from either side to make an even trade.
