UNICO LED Illuminated Binocular WF10X 4X 10X 40XR 100XR Semi-Plan MECH. Abbe N.A. 1.25. For starters these Unico microscopes are equipped with a high-eyepoint WF10X/18 eyepiece that reduces strain on your eyes even while you're wearing glasses. The eye tube itself has an independent diopter adjustment so you'll be straining less to see your subjects. The body design of the G381M Microscope is more conducive to stable viewing and it also gives you improved access to the stage controls and both focus knobs. UNICO has equipped the microscope with extra large fine and coarse focus knobs complete with tension adjustment to reduce stage drift. What's more the Unico G381M Medical Binocular Microscope features a graduated mechanical stage uses ball-bearing movement for utterly smooth adjustments that won't upset your specimen. With the Unico G380 Series Microscope your subjects will be lit up in high contrast thanks to the microscope's LED light equipped with a variable intensity rheostat wheel. The bright white light of the lamp is focused using a focusable NA 1.25 Abbe condenser which uses rack and pinion movement to shift from concentrated to diffuse lighting. All lenses on the microscope are treated with Anti-Glare Anti-Fungal and Color Correction coatings so you'll always get a clear view of the specimen without having to worry about contamination. With the standard 10x eyepiece the Unico G381 1000x Microscope can attain magnifications of up to 1000x though the 100x objective lens magnification is meant only for subjects in oil. The Binocular eyepiece of the microscope rotates a full 360 and locks in place with a thumbscrew letting you share your findings with your colleagues without moving the whole microscope. For a high powered extremely comfortable microscope that has the precision and strength to conduct all your experiments choose the Unico G380 Series Binocular High Eye-Point Micro-Scope.
