UNICO Dual-Binocular Infinity 4X 10X 40x100XR Achromat Mechanical Abbe NA 1.25 6 Volt / 20 Watt. These Unico microscopes are equipped with dual binocular heads one on either side allowing two people to use the same microscope across a table or counter. Each eyepiece has independent diopter adjustment to account for the slight differences between your eyes and they are all engineered to be more comfortable for users who wear glasses. The eyepieces of the Unico Dual Binocular 1000x Microscope are at 10x magnification and like other Unico G380 Series microscopes you can cycle between a 4x 10x 40x or 100x objective lens. The Infinity objective lenses of the Unico Dual Binocular Lab Microscope are available in achromatic or plan achromatic varieties and finished with anti-glare color correction and anti-fungal lens coatings; you'll be hard pressed to find a microscope with more accurate colors a more flat plane and fewer aberrations than the Unico Infinity Micro-Scope. Making minute adjustments is easy with the Unico G380 Infinity Dual Binocular Microscope. At the base of the microscope you'll find a fine focus and a coarse focus knob both extra-large and graduated for improved control; the focusing knobs can eliminate stage drift with the proper tension adjustment. Quality of light is easy to manipulate as well using the 1.25 NA Abbe condenser which can be focused from a diffused field to a concentrated beam using the rack and pinion design. The condenser on the Unico Dual Head Micro Scope uses the integrated LED bulb as its light source which emits enough bright white illumination to throw any subject in stark relief. UNICO has packaged these professional-grade microscopes with a five year limited warranty that covers everything but fuses and bulbs. G380 Series microscopes even come with a blue filter two replacement fuses and a plastic dust cover: enough microscope accessories to get you started. For a powerful medical microscope from Unico that two people can use at once equip your laboratory with the Unico G380 Infinity Two Binocular Medical Microscope.
