Omano OMXTLT/V10 Trinocular Microscope - The stereo microscope head provides 6.5x-45x magnification and combines with the V10 single arm boom base. The V10 is an upgrade to the popular JW11 base, its main feature being a useful, 4" horizontal, extension mechanism on the end of the boom. This convenient feature enables adjustments to the position of the microscope head without having to disengage the boom at the post.
