Check the listing for details. Microscope Stage with RSF Encoders and a Boeckeler Microcode II Digital Readout. Condition: Used. Listed at 549.00 USD. Used as shown in the pictures. Microscope stage with RSF encoders and a Boeckeler Microcode II model 2-M. The stage has a 110mm diameter dovetail mounting ring with a 76mm diameter center opening and was last used on an Olympus Vanox AH2 microscope. It should be possible to mount the stage to different microscopes by changing out the stage mounting ring. The stage has a recessed 20cm x 20cm area on the surface that originally held a glass stage plate. The stage has RSF Electronik MSA 001 linear encoders installed on the X and Y axis which feed information on stage position to the Microcode II digital readout through a Boeckeler 2-LMH. We set the stage at approximate center, zeroed the digital readout and then moved the stage to each of its limits as shown in the pictures of the digital readout. Item#424132M8C
