From my hubby's estate. He was a PhD Scientist..I found this in his office.... Stored away in a box. Looks like it has not had a lot of use. Unitron ZSB 790611 & HWF10X Lens. The discontinued UNITRON ZSB and FSB stereo microscopes provided unrivaled resolution, flatness of field and quality in their time. The ZSB and FSB are convergent objective systems. These models were discontinued in 2009, however UNITRON still maintains a limited supply of replacement parts and accessories for these models. The Unitron ZSB Zoom Stereo Binocular and the ZST Zoom Stereo Trinocular microscopes featured a parfocal twin-zooming objective system with a 0.7x through 4.5x magnification which provides a large flat field of view with excellent resolution. Magnifications were variable through the rotation of a comfortably located, smooth operating knurled ring, graduated to show varying magnifications at a glance.
The zoom ratio of 6.5:1 gave a complete magnification capability of 3.5x to 180x based on the eyepiece and auxiliary lenses that are selected.
