For a study on wall thickness of microvessels I am looking for water (or salt water) immersion 
objectives with apertures above 1. For example LEICA (LEITZ) manufactured two objectives with 
an aperture of 1.2 (90x/1.2 SW; 100x/1.2 W). These objectives are no longer available. 

Is there anyone who ones one of these objectives (or similar ones) and is willing to sell or 
lend it - or knows where I could buy one. Please contact me!
