This Zeiss LD (long distance) A Plan 20x/0.30 objective for phase contrast and Varel contrast is compatible with all Axio series microscopes.  It is designed for use on inverted tissue culture microscopes and will look through any vessel between 0-2mm thick.  It will perform both phase contrast with PH1 condenser ring and Varel contrast with Var1 condenser insert.  It is not generally recommended for fluorescence because the Varel diaphragm reduces intensity.  Objective is in like new condition.  It was bench tested on AxioVert 40 microscope and delivered crisp, sharp images as expected.    

Important Note - Use on current Zeiss microscopes with M27 objectives requires this adapter.  The RMS-M27 adapter is parfocal and parcentric with no other optical drawbacks.  Models which require this adapter are AxioObserver, AxioImager, AxioScope A1, AxioLab A1, AxioVert A1, some models of AxioVert 200.
