This binocular arm-stand stereo microscope offers three magnification powers, 20X, 40X & 80X. It comes with a versatile illumination system that provides both incident (top) lighting and transmitted (bottom) illumination. You can choose between incident illumination shining down onto the object or transmitted illumination through the frosted stage plate. The first is used for the observation of three-dimensional objects and the second for the observation of slides. This microscope offers high resolution and good depth within a broad field of view. It gives sharp clear stereo images. Its 45 degree inclined binocular head ensures an easy observation and rubber eye-guards provide further comfort. This microscopy system is a great instrument for many applications. It can be used in geology, forestry, archaeology, agriculture and biology. It is appropriate for educational purposes in hospitals and schools. It is great for the exploration of the world of surface details and fine structures of various materials like wood, metal, solder, semiconductor and stone. It is perfect for the examination of insects, plants, rocks, stamps, coins, jewel, soldered points, microelectronic components or virtually any three dimensional objects. This scope is an ideal tool for watchmaker, jeweler, engraver, dies-maker, philatelist, coin collector, students, and etc. Features: An affordable great stereo microscope45 degree inclined binocular head with locked-in eyepiecesThree magnification levels: 20X, 40X & 80XSharp stereo erect images over a wide field viewHigh quality original true colorOcular-tube with adjustable diopterAccurate alignment ensuring a fatigue-free long hour viewingRugged metal frame and arm-standFull optical glass elementsPrecise ground glass lensAll metal mechanical partsAdjustable interpupillary distanceBuilt-in both incident and transmitted illumination SystemsUpper/lower halogen lightsGS & CE approval electric apparatusExtra bulb, white/black base plate and rubber eye-guards includedManufactured under ISO 9001 Quality Control StandardExcellent Five (5) Year Manufacturer WarrantySpecifications: Head: 45 degree inclined binocularWidefield Eyepiece: WF10X and WF20XObjective: 2X & 4XDiopter Adjustment: +/-5dpInterpupillary Distance: 2-3/16" - 2-15/16"(55-75mm)Working Distance: 2-1/8" (53mm)Frosted Glass Objective Plate: 3-3/4" (96mm) in diameterWhite/Black Plastic Objective Plate: 3-3/4" (96mm) in diameterIncident Illumination: 12V/10WTransmitted Illumination: 12V/10WPower Supply: 110V (220V version available)Accessories: a pair of eye-caps, a pair of clips and a dust coverPacking List: One Binocular Microscope with Forward Arm Stand, Top & Bottom Lights and 2X & 4X ObjectivesOne Pair of 10X Widefield EyepiecesOne Pair of Widefield EyepiecesOne 3-3/4" (96mm) Frosted Glass PlateOne 3-3/4" (96mm) Plastic PlateOne Wrench for Focusing Tension AdjustmentOne Pair of Eye-guardsOne Pair of ClipsOne Spare BulbOne Dust CoverUser's Manual.
