Key Features:7X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 2X Barlow lens.Continuous zoom magnificationSuper widefield optics offer crystal clear images with a large field-of-viewSturdy pillar stand with a small footprint and extended, beveled front edgeTrinocular port for adding photo or video capabilityMonitor and capture photos and videos with the included 3MP USB 3.0 camera. Professional microscopy software for Windows, Mac, and Linux provide tools for image processing, measuring, and more.The 64-LED ring-light produces an encompassing field of bright light with reduced shadows for use with any application.This is a trinocular stereo zoom microscope with a compact stand with 12"" pillar. The stand's base has an extended, beveled front edge for comfortable hand placement. The microscope incorporates all the most excellent features of a high quality laboratory instrument. Designed to meet the demands of modern microscopy applications, this microscope exceeds all expectations. It comes with SUPER widefield optics and basic table stand. This microscope offers high resolution and good depth within a broad field of view. It provides crystal clear sharp stereo images with a 4"" (100mm) native working distance. Its 45 degree inclined ocular tubes ensure an easy observation and rubber eyeguards provide further comfort. Its trinocular port enables you to add photo or video capability.The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. A 2X Barlow lens is included, which can be mounted to the objective housing to double the magnification range to 14X-90X. This will also result in decreased working distance. The combined magnification ranges provide 7X-90X.This microscope is useful for many applications. It can be used in gemology, 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 gemstone. It is perfect for the examination of insects, plants, rocks, stamps, coins, jewel, soldered points, microelectronic components, circuit boards or virtually any three dimensional objects. This scope is an ideal tool for research labs, gemologists, collectors, engravers, watchmakers, jewelers, dies-makers, philatelists, and anyone in semiconductor or electronic industry.Monitor and capture photos and videos with the included 3.0MP USB3.0 camera. The C-mount camera is specially designed for use with microscopes, allowing you to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. The USB 3.0 connection provides greater bandwidth for faster frame-rates. A 0.37X reduction lens is included for use with 23mm-30.5mm ports to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.This package includes a 64-LED ring-light for bright and cool illumination. This lightweight illuminator mounts to the microscope's objective housing, and projects an encompassing field of light over objects, eliminating most shadows. Whether used as the sole light-source or in combination with additional illuminators, the ring-light produces a crucial light pattern for virtually any application. Energy-efficient and producing low heat, this ring-light can be used with biological specimens as well as industrial.Features :An excellent inspection microscope with contemporary table stand0.7X-4.5X Continuous Zoom Objective Lenses30mm Super Widefield Oculars4"" (100mm) Large Native Working Distance45 Degree Inclined Ocular TubesCrystal Clear Original True Color ImagesErect Sharp Stereo Images over a Super Widefield of ViewHigh Resolution with Great Flatness and ContrastAccurate Alignment Ensuring Fatigue-Free Comfortable ObservationBoth Ocular Tubes with Adjustable DioptersAdjustable Interpupillary DistanceFull Optical Glass ElementsPrecise Ground Glass LensesAll Metal Mechanical ComponentsA photo port for adding a cameraMetal Pillar Stand Finished with Stain Resistant EnamelExtended, beveled front edge of stand base allows comfortable hand placementSpecificationsMicroscope HeadHead TypeTrinocular, 45° incline, 360° rotatableOptical SystemGreenough stereoscopicInterpupillary AdjustmentCompensation-free gemel, 54-76mmOcular-port Diameter30mmDioptric AdjustmentBoth oculars, ±5dpEyepieces10XPhoto Portheight-adjustable 23mm tube, SM seriesObjective Lenses0.7X-4.5X zoomObjective Numerical Aperture0.065 @ 4.5X0.02 @ 0.7XObjective Resolution195 lp/mm @ 4.5X60 lp/mm @ 0.7XNative Field-of-View (10X Eyepieces)4.4mm-28.6mmNative Working Distance100mmAuxiliary (Barlow) Lens2X, 30mm working distanceStandStand TypePillar stand with large baseStand DimensionsBase: 12.5""x10""x0.75"" (320x280x20mm)Pillar 12"" (300mm) height, 1.25"" (32mm) diamaterFocusing-block Focus Range50mmStage Plate Diameter95mmCamera SpecificationsSensor TypeCMOSSensor Optical Format1/3""Active Pixels3M (2048 x 1534)Pixel Size2.2µm x 2.2µmActive Sensor Area4.51mm x 3.37mmShutterelectronic rolling shutterSensitivity1.9V/Lux-secSpectral Response380-650nm with IR-cut filterCapture Resolution and Maximum Framerate28fps @ 2048x153453fps @ 1024x770ConnectivityUSB 3.0Lens-mountC-mountCompensating Lens0.37XPower5VDC over USBSoftwareOS RequirementsWindows (32/64 bit) XP/Vista/7/8/10, Mac OS 10.8+, Linux kernel 3.13+Hardware RequirementsIntel Core2 2.8GHz or comparable processor, 4GB RAMFeaturesWindows VersionLive video previewCaptures still images and videoTime-lapse captureExposure and white-balance controlsDark-field correctionDigital binningImage processingMeasurement tools, including lines, arcs, polygonsSegmentation and counting toolsImage-stitching, extended depth-of-field, HDRFluorescence color-mappingMac/Linux VersionsLive video previewCaptures still images and videoExposure controlColor adjustmentMeasurement tools, including lines, arcs, polygonsPacking List:One trinocular stereo microscope headOne photo port 10X eyepiece(s)One 2X Barlow lensOne pair eye-guardsOne stand baseOne stand pillarOne focusing blockOne pair stage clipsOne black/white stage plateOne hex wrenchScrews and washersOne C-mount USB cameraOne 0.37X reduction lensTwo sizing adaptersOne USB 3.0 Type B to type A cableOne software CDOne LED ring-lightOne AC adapterOne ring-light mounting adapter
