OLYMPUS SZH-Bi45N Binocular Observation Tube / Head for SZH, SZH10 Stereo Microscope. Should also work with SZX series, but I can't confirm it.
This Observation Tube and Eyepieces was a 2nd observation tube from a dual-microscope teaching setup that was converted into a single microscope - see the last photo. Only the observation tube / binocular head assembly and eyepieces are included! I tested it on the primary microscope, and it appears to be working, with clear image and perfect alignment. Also, I would not reject a reasonable offer. The dual microscope setup was parted to create a single microscope, and other parts are for sale see my other items.
