The Zeiss Plan Apo 63x/1.40 oil is Zeiss' flagship objective lens for high resolution imaging.  Extremely high numerical aperture, wide field of view, excellent fluorescence sensitivity, apochromatically color corrected and perfectly flat edge to edge.  This is also the "DIC" version of this lens so it has been specially selected for its excellent strain characteristics.  Zeiss p/n 420782-9900-000 which is the currently available version new.  Compatible with LSM confocal, Apotome, deconvolution, Differential Interference Contrast (DIC) - this is an all around performer.  We have inspected this objective very closely and put it through testing on an AxioObserver with Apotome and it performs as new.  Optics are pristine.  M27 thread.  If you have Axiovert 200, please ensure that your version has M27 nosepiece - the other objectives will have a 42- part number instead of 44- part number on them.   

Objective is in excellent condition with flawless optics and will perform like new. There are some minor cosmetic marks on tip which can be seen on close inspection and a minor cosmetic mark on the blue barrel band - none of which affect performance.  Tested on AxioImager stand with excellent results as would be expected.  

Zeiss list price new = $7967.  This is an excellent opportunity to work with with the famous Zeiss 63x Plan Apo oil objective with all the performance of a new objective but less than half the price.
