Description

Aus Jena 0.5x Auxiliary Lens with Pole Extension for Technival 2/ Citoval 2 Microscope
Very good condition.  Lens is flange-mount and fits over flange at the bottom of Technival 2/ Citoval 2 stereo microscope body and clamps in place with thumscrew.  Extension pole is to compensate for the longer working distance of the lens (sorry, I do not have optical data).  Extention pole adds 105.5 mm and features a set screw and detent in the pin area to receive the set screw of the original stand to reduce the chance of unwanted rotation.  Pole diameter is 29mm, pin section is 15mm diameter x 29mm long
